IoT systems allow users to achieve deeper automation, analysis, and integration within a system.
They improve the reach of these areas and their accuracy. IoT utilizes existing and emerging
technology for sensing, networking, and robotics.
IoT exploits recent advances in software, falling hardware prices, and modern attitudes towards
technology. Its new and advanced elements bring major changes in the delivery of products,
goods, and services; and the social, economic, and political impact of those changes.
IoT−KeyFeatures
The most important features of IoT include artificial intelligence, connectivity, sensors, active
engagement, and small device use. A brief review of these features is given below:
 AI – IoT essentially makes virtually anything “smart”, meaning it enhances every aspect
of life with the power of data collection, artificial intelligence algorithms, and networks.
This can mean something as simple as enhancing your refrigerator and cabinets to detect
when milk and your favorite cereal run low, and to then place an order with your preferred
grocer.
 Connectivity – New enabling technologies for networking, and specifically IoT
networking, mean networks are no longer exclusively tied to major providers. Networks
can exist on a much smaller and cheaper scale while still being practical. IoT creates
these small networks between its system devices.
 Sensors – IoT loses its distinction without sensors. They act as defining instruments
which transform IoT from a standard passive network of devices into an active system
capable of real-world integration.
 Active Engagement – Much of today's interaction with connected technology happens
through passive engagement. IoT introduces a new paradigm for active content, product,
or service engagement.
 Small Devices – Devices, as predicted, have become smaller, cheaper, and more
powerful over time. IoT exploits purpose-built small devices to deliver its precision,
scalability, and versatility.
IoT−Advantages
The advantages of IoT span across every area of lifestyle and business. Here is a list of some of
the advantages that IoT has to offer:
 Improved Customer Engagement – Current analytics suffer from blind-spots and
significant flaws in accuracy; and as noted, engagement remains passive. IoT completely
transforms this to achieve richer and more effective engagement with audiences.
 Technology Optimization – The same technologies and data which improve the
customer experience also improve device use, and aid in more potent improvements to
technology. IoT unlocks a world of critical functional and field data.
1. IoT − Overview

Internet of Things

 Reduced Waste – IoT makes areas of improvement clear. Current analytics give us
superficial insight, but IoT provides real-world information leading to more effective
management of resources.
 Enhanced Data Collection – Modern data collection suffers from its limitations and its
design for passive use. IoT breaks it out of those spaces, and places it exactly where
humans really want to go to analyze our world. It allows an accurate picture of everything.
IoT−Disadvantages
Though IoT delivers an impressive set of benefits, it also presents a significant set of challenges.
Here is a list of some its major issues:
 Security – IoT creates an ecosystem of constantly connected devices communicating
over networks. The system offers little control despite any security measures. This leaves
users exposed to various kinds of attackers.
 Privacy – The sophistication of IoT provides substantial personal data in extreme detail
without the user's active participation.
 Complexity – Some find IoT systems complicated in terms of design, deployment, and
maintenance given their use of multiple technologies and a large set of new enabling
technologies.
 Flexibility – Many are concerned about the flexibility of an IoT system to integrate easily
with another. They worry about finding themselves with several conflicting or locked
systems.
 Compliance – IoT, like any other technology in the realm of business, must comply with
regulations. Its complexity makes the issue of compliance seem incredibly challenging
when many consider standard software compliance a battle.

The hardware utilized in IoT systems includes devices for a remote dashboard, devices for
control, servers, a routing or bridge device, and sensors. These devices manage key tasks and
functions such as system activation, action specifications, security, communication, and
detection to support-specific goals and actions.
IoT−Sensors
The most important hardware in IoT might be its sensors. These devices consist of energy
modules, power management modules, RF modules, and sensing modules. RF modules manage
communications through their signal processing, WiFi, ZigBee, Bluetooth, radio transceiver,
duplexer, and BAW.
The sensing module manages sensing through assorted active and passive measurement
devices. Here is a list of some of the measurement devices used in IoT:
Devices
accelerometers temperature sensors
magnetometers proximity sensors
gyroscopes image sensors
acoustic sensors light sensors
pressure sensors gas RFID sensors
humidity sensors micro flow sensors

WearableElectronics
Wearable electronic devices are small devices worn on the head, neck, arms, torso, and feet.
Smartwatches not only help us stay connected, but as a part of an IoT
system, they allow access needed for improved productivity.
Current smart wearable devices include:
 Head – Helmets, glasses
 Neck – Jewelry, collars
 Arm – Watches, wristbands, rings
 Torso – Clothing, backpacks
 Feet – Socks, shoes

Internet of Things

Smart glasses help us enjoy more of the media and services we value, and
when part of an IoT system, they allow a new approach to productivity.
StandardDevices
The desktop, tablet, and cellphone remain integral parts of IoT as the command center and
remotes.
 The desktop provides the user with the highest level of control over the system and its
settings.
 The tablet provides access to the key features of the system in a way resembling the
desktop, and also acts as a remote.
 The cellphone allows some essential settings modification and also provides remote
functionality.
Other key connected devices include standard network devices like routers and switches.

IoT software addresses its key areas of networking and action through platforms, embedded
systems, partner systems, and middleware. These individual and master applications are
responsible for data collection, device integration, real-time analytics, and application and
process extension within the IoT network. They exploit integration with critical business systems
(e.g., ordering systems, robotics, scheduling, and more) in the execution of related tasks.
Data Collection
This software manages sensing, measurements, light data filtering, light data security, and
aggregation of data. It uses certain protocols to aid sensors in connecting with real-time,
machine-to-machine networks. Then it collects data from multiple devices and distributes it in
accordance with settings. It also works in reverse by distributing data over devices. The system
eventually transmits all collected data to a central server.
Device Integration
Software supporting integration binds (dependent relationships) all system devices to create the
body of the IoT system. It ensures the necessary cooperation and stable networking between
devices. These applications are the defining software technology of the IoT network because
without them, it is not an IoT system. They manage the various applications, protocols, and
limitations of each device to allow communication.
Real-Time Analytics
These applications take data or input from various devices and convert it into viable actions or
clear patterns for human analysis. They analyze information based on various settings and
designs in order to perform automation-related tasks or provide the data required by industry.
Application and Process Extension
These applications extend the reach of existing systems and software to allow a wider, more
effective system. They integrate predefined devices for specific purposes such as allowing certain
mobile devices or engineering instruments access. It supports improved productivity and more
accurate data collection.
3. IoT − Software

Internet of Things

IoT primarily exploits standard protocols and networking technologies. However, the major
enabling technologies and protocols of IoT are RFID, NFC, low-energy Bluetooth, low-energy
wireless, low-energy radio protocols, LTE-A, and WiFi-Direct. These technologies support the
specific networking functionality needed in an IoT system in contrast to a standard uniform
network of common systems.
NFC and RFID
RFID (radio-frequency identification) and NFC (near-field communication) provide simple, low-
energy, and versatile options for identity and access tokens, connection bootstrapping, and
payments.
 RFID technology employs 2-way radio transmitter-receivers to identify and track tags
associated with objects.
 NFC consists of communication protocols for electronic devices, typically a mobile device
and a standard device.
Low-Energy Bluetooth
This technology supports the low-power, long-use need of IoT function while exploiting a
standard technology with native support across systems.
Low-Energy Wireless
This technology replaces the most power hungry aspect of an IoT system. Though sensors and
other elements can power down over long periods, communication links (i.e., wireless) must
remain in listening mode. Low-energy wireless not only reduces consumption, but also extends
the life of the device through less use.
Radio Protocols
ZigBee, Z-Wave, and Thread are radio protocols for creating low-rate private area networks.
These technologies are low-power, but offer high throughput unlike many similar options. This
increases the power of small local device networks without the typical costs.
LTE-A
LTE-A, or LTE Advanced, delivers an important upgrade to LTE technology by increasing not only
its coverage, but also reducing its latency and raising its throughput. It gives IoT a tremendous
power through expanding its range, with its most significant applications being vehicle, UAV,
and similar communication.
WiFi-Direct
WiFi-Direct eliminates the need for an access point. It allows P2P (peer-to-peer) connections
with the speed of WiFi, but with lower latency. WiFi-Direct eliminates an element of a network
that often bogs it down, and it does not compromise on speed or throughput.
4. IoT − Technology and Protocols

Internet of Things
8
IoT has applications across all industries and markets. It spans user groups from those who want
to reduce energy use in their home to large organizations who want to streamline their
operations. It proves not just useful, but nearly critical in many industries as technology
advances and we move towards the advanced automation imagined in the distant future.
Engineering,Industry,andInfrastructure
Applications of IoT in these areas include improving production, marketing, service delivery, and
safety. IoT provides a strong means of monitoring various processes; and real transparency
creates greater visibility for improvement opportunities.
The deep level of control afforded by IoT allows rapid and more action on those opportunities,
which include events like obvious customer needs, nonconforming product, malfunctions in
equipment, problems in the distribution network, and more.
Example
Joan runs a manufacturing facility that makes shields for manufacturing equipment. When
regulations change for the composition and function of the shields, the new appropriate
requirements are automatically programmed in production robotics, and engineers are alerted
about their approval of the changes.
GovernmentandSafety
IoT applied to government and safety allows improved law enforcement, defense, city planning,
and economic management. The technology fills in the current gaps, corrects many current
flaws, and expands the reach of these efforts. For example, IoT can help city planners have a
clearer view of the impact of their design, and governments have a better idea of the local
economy.
Example
Joan lives in a small city. She’s heard about a recent spike in crime in her area, and worries
about coming home late at night.
Local law enforcement has been alerted about the new “hot” zone through system flags, and
they’ve increases their presence. Area monitoring devices have detected suspicious behavior,
and law enforcement has investigated these leads to prevent crimes.
HomeandOffice
In our daily lives, IoT provides a personalized experience from the home to the office to the
organizations we frequently do business with. This improves our overall satisfaction, enhances
productivity, and improves our health and safety. For example, IoT can help us customize our
office space to optimize our work.
5. IoT − Common Uses

Internet of Things
9
Example
Joan works in advertising. She enters her office, and it recognizes her face. It adjusts the lighting
and temperature to her preference. It turns on her devices and opens applications to her last
working points.
Her office door detected and recognized a colleague visiting her office multiple times before she
arrived. Joan’s system opens this visitor’s messages automatically.
HealthandMedicine
IoT pushes us towards our imagined future of medicine which exploits a highly integrated
network of sophisticated medical devices. Today, IoT can dramatically enhance medical research,
devices, care, and emergency care. The integration of all elements provides more accuracy,
more attention to detail, faster reactions to events, and constant improvement while reducing
the typical overhead of medical research and organizations.
Example
Joan is a nurse in an emergency room. A call has come in for a man wounded in an altercation.
The system recognized the patient and pulls his records. On the scene, paramedic equipment
captures critical information automatically sent to the receiving parties at the hospital. The
system analyzes the new data and current records to deliver a guiding solution. The status of
the patient is updated every second in the system during his transport. The system prompts
Joan to approve system actions for medicine distribution and medical equipment preparation.

Internet of Things
10
The applications of IoT in media and advertising involve a customized experience in which the
system analyzes and responds to the needs and interests of each customer. This includes their
general behavior patterns, buying habits, preferences, culture, and other characteristics.
Marketing and Content Delivery
IoT functions in a similar and deeper way to current technology, analytics, and big data. Existing
technology collects specific data to produce related metrics and patterns over time, however,
that data often lacks depth and accuracy. IoT improves this by observing more behaviors and
analyzing them differently.
 This leads to more information and detail, which delivers more reliable metrics and
patterns.
 It allows organizations to better analyze and respond to customer needs or preferences.
 It improves business productivity and strategy, and improves the consumer experience
by only delivering relevant content and solutions.
6. IoT − Media, Marketing, & Advertising

Internet of Things
11
Improved Advertising
Current advertising suffers from excess and poor targeting. Even with today's analytics, modern
advertising fails. IoT promises different and personalized advertising rather than one-size-fits-
all strategies. It transforms advertising from noise to a practical part of life because consumers
interact with advertising through IoT rather than simply receiving it. This makes advertising
more functional and useful to people searching the marketplace for solutions or wondering if
those solutions exist.

Internet of Things
12
The applications of IoT in environmental monitoring are broad: environmental protection,
extreme weather monitoring, water safety, endangered species protection, commercial farming,
and more. In these applications, sensors detect and measure every type of environmental
change.
Air and Water Pollution
Current monitoring technology for air and water safety primarily uses manual labor along with
advanced instruments, and lab processing. IoT improves on this technology by reducing the
need for human labor, allowing frequent sampling, increasing the range of sampling and
monitoring, allowing sophisticated testing on-site, and binding response efforts to detection
systems. This allows us to prevent substantial contamination and related disasters.
Extreme Weather
Though powerful, advanced systems currently in use allow deep monitoring, they suffer from
using broad instruments, such as radar and satellites, rather than more granular solutions. Their
instruments for smaller details lack the same accurate targeting of stronger technology.
New IoT advances promise more fine-grained data, better accuracy, and flexibility. Effective
forecasting requires high detail and flexibility in range, instrument type, and deployment. This
allows early detection and early responses to prevent loss of life and property.
Commercial Farming
Today's sophisticated commercial farms have exploited advanced technology and biotechnology
for quite some time, however, IoT introduces more access to deeper automation and analysis.
7. IoT − Environmental Monitoring

Internet of Things
13
Much of commercial farming, like weather monitoring, suffers from a lack of precision and
requires human labor in the area of monitoring. Its automation also remains limited.
IoT allows operations to remove much of the human intervention in system function, farming
analysis, and monitoring. Systems detect changes to crops, soil, environment, and more. They
optimize standard processes through analysis of large, rich data collections. They also prevent
health hazards (e.g., e. coli) from happening and allow better control.

Internet of Things
14
Manufacturing technology currently in use exploits standard technology along with modern
distribution and analytics. IoT introduces deeper integration and more powerful analytics. This
opens the world of manufacturing in a way never seen before, as organizations become fully-
developed for product delivery rather than a global network of suppliers, makers, and
distributors loosely tied together.
Intelligent Product Enhancements
Much like IoT in content delivery, IoT in manufacturing allows richer insight in real-time. This
dramatically reduces the time and resources devoted to this one area, which traditionally
requires heavy market research before, during, and well after the products hit the market.
IoT also reduces the risks associated with launching new or modified products because it provides
more reliable and detailed information. The information comes directly from market use and
buyers rather than assorted sources of varied credibility.
Dynamic Response to Market Demands
Supplying the market requires maintaining a certain balance impacted by a number of factors
such as economy state, sales performance, season, supplier status, manufacturing facility
status, distribution status, and more. The expenses associated with supply present unique
challenges given today's global partners. The associated potential or real losses can dramatically
impact business and future decisions.
IoT manages these areas through ensuring fine details are managed more at the system level
rather than through human evaluations and decisions. An IoT system can better assess and
control the supply chain (with most products), whether demands are high or low.
Lower Costs, Optimized Resource Use, and Waste Reduction
IoT offers a replacement for traditional labor and tools in a production facility and in the overall
chain which cuts many previously unavoidable costs; for example, maintenance checks or tests
traditionally requiring human labor can be performed remotely with instruments and sensors of
an IoT system.
IoT also enhances operation analytics to optimize resource use and labor, and eliminate various
types of waste, e.g., energy and materials. It analyzes the entire process from the source point
to its end, not just the process at one point in a particular facility, which allows improvement to
have a more substantial impact. It essentially reduces waste throughout the network, and
returns those savings throughout.
8. IoT − Manufacturing Applications

Internet of Things
15
This XRS relay box connects all truck devices (e.g., diagnostics and
driver cell) to the XRS fleet management supporting software, which
allows data collection.
Improved Facility Safety
A typical facility suffers from a number of health and safety hazards due to risks posed by
processes, equipment, and product handling. IoT aids in better control and visibility. Its
monitoring extends throughout the network of devices for not only performance, but for
dangerous malfunctions and usage. It aids (or performs) analysis and repair, or correction, of
critical flaws.
Product Safety
Even the most sophisticated system cannot avoid malfunctions, nonconforming product, and
other hazards finding their way to market. Sometimes these incidents have nothing to do with
the manufacturing process, and result from unknown conflicts.
In manufacturing, IoT helps in avoiding recalls and controlling nonconforming or dangerous
product distribution. Its high level of visibility, control, and integration can better contain any
issues that appear.

Internet of Things
16
The optimization qualities of IoT in manufacturing also apply to energy consumption. IoT allows
a wide variety of energy control and monitoring functions, with applications in devices,
commercial and residential energy use, and the energy source. Optimization results from the
detailed analysis previously unavailable to most organizations and individuals.
Residential Energy
The rise of technology has driven energy costs up. Consumers search for ways to reduce or
control consumption. IoT offers a sophisticated way to analyze and optimize use not only at
device level, but throughout the entire system of the home. This can mean simple switching off
or dimming of lights, or changing device settings and modifying multiple home settings to
optimize energy use.
IoT can also discover problematic consumption from issues like older appliances, damaged
appliances, or faulty system components. Traditionally, finding such problems required the use
of often multiple professionals.
Commercial Energy
Energy waste can easily and quietly impact business in a major way, given the tremendous
energy needs of even small organizations. Smaller organizations wrestle with balancing costs of
business while delivering a product with typically smaller margins, and working with limited
funding and technology. Larger organizations must monitor a massive, complex ecosystem of
energy use that offers few simple, effective solutions for energy use management.
A smart-meter still requires a reader to visit
the site. This automated meter reader
makes visits unnecessary, and also allows
energy companies to bill based on real-time
data instead of estimates over time.
IoT simplifies the process of energy monitoring and management while maintaining a low cost
and high level of precision. It addresses all points of an organization's consumption across
devices. Its depth of analysis and control provides organizations with a strong means of
managing their consumption for cost shaving and output optimization. IoT systems discover

energy issues in the same way as functional issues in a complex business network, and provide
solutions.
Reliability
The analytics and action delivered by IoT also help to ensure system reliability. Beyond
consumption, IoT prevents system overloads or throttling. It also detects threats to system
performance and stability, which protects against losses such as downtime, damaged equipment,
and injuries.

Internet of Things
18
IoT systems applied to healthcare enhance existing technology, and the general practice of
medicine. They expand the reach of professionals within a facility and far beyond it. They
increase both the accuracy and size of medical data through diverse data collection from large
sets of real-world cases. They also improve the precision of medical care delivery through more
sophisticated integration of the healthcare system.
Research
Much of current medical research relies on resources lacking critical real-world information. It
uses controlled environments, volunteers, and essentially leftovers for medical examination. IoT
opens the door to a wealth of valuable information through real-time field data, analysis, and
testing.
IoT can deliver relevant data superior to standard analytics through integrated instruments
capable of performing viable research. It also integrates into actual practice to provide more key
information. This aids in healthcare by providing more reliable and practical data, and better
leads; which yields better solutions and discovery of previously unknown issues.
It also allows researchers to avoid risks by gathering data without manufactured scenarios and
human testing.
Devices
Current devices are rapidly improving in precision, power, and availability; however, they still
offer less of these qualities than an IoT system integrating the right system effectively. IoT
unlocks the potential of existing technology, and leads us toward new and better medical device
solutions.
IoT closes gaps between equipment and the way we deliver healthcare by creating a logical
system rather than a collection of tools. It then reveals patterns and missing elements in
healthcare such as obvious necessary improvements or huge flaws.
The ClearProbe portable connected ultrasound device can use any
computer anywhere as a supporting machine. The device sends all
imaging records to the master system.
10. IoT − Healthcare Applications

Internet of Things
19
Care
Perhaps the greatest improvement IoT brings to healthcare is in the actual practice of medicine
because it empowers healthcare professionals to better use their training and knowledge to solve
problems. They utilize far better data and equipment, which gives them a window into blind
spots and supports more swift, precise actions. Their decision-making is no longer limited by the
disconnects of current systems, and bad data.
IoT also improves their professional development because they actually exercise their talent
rather than spending too much time on administrative or manual tasks. Their organizational
decisions also improve because technology provides a better vantage point.
Medical Information Distribution
One of the challenges of medical care is the distribution of accurate and current information to
patients. Healthcare also struggles with guidance given the complexity of following guidance.
IoT devices not only improve facilities and professional practice, but also health in the daily lives
of individuals.
IoT devices give direct, 24/7 access to the patient in a less intrusive way than other options.
They take healthcare out of facilities and into the home, office, or social space. They empower
individuals in attending to their own health, and allow providers to deliver better and more
granular care to patients. This results in fewer accidents from miscommunication, improved
patient satisfaction, and better preventive care.
Emergency Care
The advanced automation and analytics of IoT allows more powerful emergency support
services, which typically suffer from their limited resources and disconnect with the base facility.
It provides a way to analyze an emergency in a more complete way from miles away. It also
gives more providers access to the patient prior to their arrival. IoT gives providers critical
information for delivering essential care on arrival. It also raises the level of care available to a
patient received by emergency professionals. This reduces the associated losses, and improves
emergency healthcare.

Internet of Things
20
IoT applied to buildings and various structures allows us to automate routine residential and
commercial tasks and needs in a way that dramatically improves living and working
environments. This, as seen with manufacturing and energy applications, reduces costs,
enhances safety, improves individual productivity, and enhances quality of life.
Environment and Conditioning
One of the greatest challenges in the engineering of buildings remains management of
environment and conditions due to many factors at work. These factors include building
materials, climate, building use, and more. Managing energy costs receives the most attention,
but conditioning also impacts the durability and state of the structure.
IoT aids in improving structure design and managing existing structures through more accurate
and complete data on buildings. It provides important engineering information such as how well
a material performs as insulation in a particular design and environment.
Health and Safety
Buildings, even when constructed with care, can suffer from certain health and safety issues.
These issues include poor performing materials, flaws that leave the building vulnerable to
extreme weather, poor foundations, and more.
The Boss 220 smart plug allows the user to monitor, control, optimize, and
automate all plug-in devices. Users employ their mobile device or desktop to
view performance information and control devices from anywhere.
11. IoT − Building/Housing Applications

Internet of Things
21
Current solutions lack the sophistication needed to detect minor issues before they become
major issues, or emergencies. IoT offers a more reliable and complete solution by observing
issues in a fine-grained way to control dangers and aid in preventing them; for example, it can
measure changes in a system's state impacting fire safety rather than simply detecting smoke.
Productivity and Quality of Life
Beyond safety or energy concerns, most people desire certain comforts from housing or
commercial spaces like specific lighting and temperature. IoT enhances these comforts by
allowing faster and easier customizing.
Adjustments also apply to the area of productivity. They personalize spaces to create an
optimized environment such as a smart office or kitchen prepared for a specific individual.

Internet of Things
22
At every layer of transportation, IoT provides improved communication, control, and data
distribution. These applications include personal vehicles, commercial vehicles, trains, UAVs, and
other equipment. It extends throughout the entire system of all transportation elements such as
traffic control, parking, fuel consumption, and more.
Rails and Mass Transit
Current systems deliver sophisticated integration and performance, however, they employ older
technology and approaches to MRT. The improvements brought by IoT deliver more complete
control and monitoring. This results in better management of overall performance, maintenance
issues, maintenance, and improvements.
Mass transit options beyond standard MRT suffer from a lack of the integration necessary to
transform them from an option to a dedicated service. IoT provides an inexpensive and advanced
way to optimize performance and bring qualities of MRT to other transportation options like
buses. This improves services and service delivery in the areas of scheduling, optimizing
transport times, reliability, managing equipment issues, and responding to customer needs.
Road
The primary concerns of traffic are managing congestion, reducing accidents, and parking. IoT
allows us to better observe and analyze the flow of traffic through devices at all traffic
observation points. It aids in parking by making storage flow transparent when current methods
offer little if any data.
12. IoT − Transportation Applications

Internet of Things
23
This smart road sign receives data and modifications to better inform drivers and
prevent congestion or accidents.
Accidents typically result from a number of factors, however, traffic management impacts their
frequency. Construction sites, poor rerouting, and a lack of information about traffic status are
all issues that lead to incidents. IoT provides solutions in the form of better information sharing
with the public, and between various parties directly affecting road traffic.
Automobile
Many in the automotive industry envision a future for cars in which IoT technology makes cars
“smart,” attractive options equal to MRT. IoT offers few significant improvements to personal
vehicles. Most benefits come from better control over related infrastructure and the inherent
flaws in automobile transport; however, IoT does improve personal vehicles as personal spaces.
IoT brings the same improvements and customization to a vehicle as those in the home.
Commercial Transportation
Transportation benefits extend to business and manufacturing by optimizing the transport arm
of organizations. It reduces and eliminates problems related to poor fleet management through
better analytics and control such as monitoring idling, fuel consumption, travel conditions, and
travel time between points. This results in product transportation operating more like an aligned
service and less like a collection of contracted services.

Internet of Things
24
IoT in the classroom combines the benefits of IoT in content delivery, business, and healthcare.
It customizes and enhances education by allowing optimization of all content and forms of
delivery. It enables educators to give focus to individuals and their method. It also reduces costs
and labor of education through automation of common tasks outside of the actual education
process.
Education Organizations
Education organizations typically suffer from limited funding, labor issues, and poor attention to
actual education. They, unlike other organizations, commonly lack or avoid analytics due to their
funding issues and the belief that analytics do not apply to their industry.
IoT not only provides valuable insight, but it also democratizes that information through low-
cost, low-power small devices, which still offer high performance. This technology aids in
managing costs, improving the quality of education, professional development, and facility
management improvement through rich examinations of key areas:
 Student response, performance, and behavior
 Instructor response, performance, and behavior
 Facility monitoring and maintenance
 Data from other facilities
Data informs them about ineffective strategies and actions, whether educational efforts or facility
qualities. Removing these roadblocks makes them more effective.
Educators
Information provided by IoT empowers educators to deliver improved education. They have a
window into the success of their strategies, their students' perspective, and other aspects of
their performance. IoT relieves them of administrative and management duties, so they can
focus on their mission. It automates manual and clerical labor, and facilitates supervising
through features like system flags or controls to ensure students remain engaged.
13. IoT − Education Applications

Internet of Things
25
A school in Richmond, California, embeds RFID chips in ID cards to track the presence of
students. Even if students are not present for check-in, the system will track and log
their presence on campus.
IoT provides instructors with easy access to powerful educational tools. Educators can use IoT
to perform as a one-on-one instructor providing specific instructional designs for each pupil; for
example, using data to determine the most effective supplements for each student, and auto-
generating content from lesson materials on-demand for any student.
The application of technology improves the professional development of educators because they
truly see what works, and learn to devise better strategies, rather than simply repeating old or
ineffective methods.
IoT also enhances the knowledge base used to devise education standards and practices.
Education research suffers from accuracy issues and a general lack of data. IoT introduces large
high quality, real-world datasets into the foundation of educational design. This comes from IoT's
unique ability to collect enormous amounts of varied data anywhere.
Personalized Education
IoT facilitates the customization of education to give every student access to what they need.
Each student can control their experience and participate in instructional design, and much of
this happens passively. The student simply utilizes the system, and performance data primarily
shapes their design. This combined with organizational and educator optimization delivers highly
effective education while reducing costs.

IoT supports the development of smart nations and smart cities. This includes enhancement of
infrastructure previously discussed (e.g., healthcare, energy, transportation, etc.), defense, and
also the engineering and maintenance of communities.
City Planning and Management
Governing bodies and engineers can use IoT to analyze the often complex aspects of city
planning and management. IoT simplifies examining various factors such as population growth,
zoning, mapping, water supply, transportation patterns, food supply, social services, and land
use. It gathers detailed data in these areas and produces more valuable and accurate information
than current analytics given its ability to actually “live” with people in a city.
Smart trashcans in New York tell garbage collectors when they need to be emptied.
They optimize trash service by ensuring drivers only make necessary stops, and
drivers modify their route to reduce fuel consumption.
14. IoT − Government Applications

Internet of Things
27
In the area of management, IoT supports cities through its implementation in major services
and infrastructure such as transportation and healthcare. It also aids in other key areas like
water control, waste management, and emergency management. Its real-time and detailed
information facilitate more prompt decisions in contrast to the traditional process plagued by
information lag, which can be critical in emergency management.
Standard state services are also improved by IoT, which can automate otherwise slow processes
and trim unnecessary state expenses; for example, it can automate motor vehicle services for
testing, permits, and licensing.
IoT also aids in urban improvement by skipping tests or poor research, and providing functional
data for how the city can be optimized. This leads to faster and more meaningful changes.
Creating Jobs
IoT offers thorough economic analysis. It makes previous blind spots visible and supports better
economic monitoring and modeling. It analyzes industry and the marketplace to spot
opportunities for growth and barriers.
National Defense
National threats prove diverse and complicated. IoT augments armed forces systems and
services, and offers the sophistication necessary to manage the landscape of national defense.
It supports better protection of borders through inexpensive, high performance devices for rich
control and observation.
IoT automates the protection tasks typically spread across several departments and countless
individuals. It achieves this while improving accuracy and speed.

Internet of Things
28
IoT enhances law enforcement organizations and practice, and improves the justice system. The
technology boosts transparency, distributes critical data, and removes human intervention
where it proves unnecessary.
Policing
Law enforcement can be challenging. IoT acts as an instrument of law enforcement which
reduces manual labor and subjective decisions through better data, information sharing, and
advanced automation. IoT systems shave costs by reducing human labor in certain areas such
as certain traffic violations.
IoT aids in creating better solutions to problems by using technology in the place of force; for
example, light in-person investigations of suspicious activities can be replaced with remote
observation, logged footage of violations, and electronic ticketing. It also reduces corruption by
removing human control and opinion for some violations.
This dart planted in a truck gate prevents dangerous car chases. A
patrol car launches the tracking dart which pierces the vehicle. Then
the main system receives all data needed to locate the vehicle.
Court System
Current court systems utilize traditional technology and resources. They generally do not exploit
modern analytics or automation outside of minor legal tasks. IoT brings superior analytics, better
evidence, and optimized processes to court systems which accelerate processes, eliminate
excessive procedures, manage corruption, reduce costs, and improve satisfaction.
15. IoT − Law Enforcement Applications

Internet of Things
29
In the criminal court system, this can result in a more effective and fair system. In routine court
services, it introduces automation similar to that of common government office services; for
example, IoT can automate forming an LLC.
IoT combined with new regulations can remove lawyers from many common legal tasks or
reduce the need for their involvement. This reduces costs and accelerates many processes which
often require months of traversing legal procedures and bureaucracy.

Consumers benefit personally and professionally from the optimization and data analysis of IoT.
IoT technology behaves like a team of personal assistants, advisors, and security. It enhances
the way we live, work, and play.
Home
IoT takes the place of a full staff:
 Butler – IoT waits for you to return home, and ensures your home remains fully
prepared. It monitors your supplies, family, and the state of your home. It takes actions
to resolve any issues that appear.
 Chef – An IoT kitchen prepares meals or simply aids you in preparing them.
 Nanny – IoT can somewhat act as a guardian by controlling access, providing supplies,
and alerting the proper individuals in an emergency.
 Gardner – The same IoT systems of a farm easily work for home landscaping.
 Repairman – Smart systems perform key maintenance and repairs, and also request
them.
 Security Guard – IoT watches over you 24/7. It can observe suspicious individuals miles
away, and recognize the potential of minor equipment problems to become disasters well
before they do.

16. IoT − Consumer Applications

Internet of Things
31
Work
A smart office or other workspace combines customization of the work environment with smart
tools. IoT learns about you, your job, and the way you work to deliver an optimized environment.
This results in practical accommodations like adjusting the room temperature, but also more
advanced benefits like modifying your schedule and the tools you use to increase your output
and reduce your work time. IoT acts as a manager and consultant capable of seeing what you
cannot.
Play
IoT learns as much about you personally as it does professionally. This enables the technology
to support leisure:
 Culture and Night Life – IoT can analyze your real-world activities and response to
guide you in finding more of the things and places you enjoy such as recommending
restaurants and events based on your preferences and experiences.
 Vacations – Planning and saving for vacations proves difficult for some, and many utilize
agencies, which can be replaced by IoT.
 Products and Services – IoT offers better analysis of the products you like and need
than current analytics based on its deeper access. It integrates with key information like
your finances to recommend great solutions.

Thingworx is a platform for the rapid development and deployment of smart, connected devices.
Its set of integrated IoT development tools support connectivity, analysis, production, and other
aspects of IoT development.
It offers Vuforia for implementing augmented reality development, and Kepware for industrial
connectivity. KEPServerEX provides a single point for data distribution, and facilitates
interoperability when partnered with a ThingWorx agent.
Components
Thingworx offers several key tools for building applications. These tools include the Composer,
the Mashup Builder, storage, a search engine, collaboration, and connectivity. The Composer
provides a modeling environment for design testing. The Mashup Builder delivers easy dashboard
building through common components (or widgets); for example, buttons, lists, wikis, gauges,
and etc.
Thingworx uses a search engine known as SQUEAL, meaning Search, Query, and Analysis. Users
employ SQUEAL in analyzing and filtering data, and searching records.
Interface
The ThingWorx platform uses certain terms you must familiarize yourself with. In the main
screen's top menu, you search for entities or create them. “Entity” refers to something created
in ThingWorx. You can also import/export files and perform various operations on them.
In the left menu, you find entity groups, which are used to produce models and visualize data;
and manage storage, collaboration, security, and the system.
17. IoT − ThingWorx

Internet of Things
33
When you select the Modeling category in the menu, you begin the process by creating an entity.
The entity can be any physical device or software element, and it produces an event on changes
to its property values; for example, a sensor detects a temperature change. You can set events
to trigger actions through a subscription which makes decisions based on device changes.
Data Shapes consist of one or more fields. They describe the data structure of custom events,
infotables, streams, and datatables. Data shapes are considered entities.
Thing Templates and Thing Shapes allow developers to avoid repeating device property
definitions in large IoT systems. Developers create Thing Templates to allow new devices to
inherit properties. They use Thing Shapes to define Templates, properties, or execute services.
Note a Thing only inherits properties, services, events, and other qualities from a single
template, however, Things and templates can inherit properties from multiple Thing Shapes.

Internet of Things
34
Development
ThingWorx actually requires very little programming. Users connect devices, establish a data
source, establish device behaviors, and build an interface without any coding. It also offers
scalability appropriate for both hobbyist projects and industrial applications.

Cisco Virtualized Packet Core (VPC) is a technology providing all core services for 4G, 3G, 2G,
WiFi, and small cell networks. It delivers networking functionality as virtualized services to allow
greater scalability and faster deployment of new services at a reduced cost. It distributes and
manages packet core functions across all resources, whether virtual or physical. Its key features
include packet core service consolidation, dynamic scaling, and system agility.
Its technology supports IoT by offering network function virtualization, SDN (software-defined
networking), and rapid networked system deployment. This proves critical because its
virtualization and SDN support low-power, high flow networking, and the simple deployment of
a wide variety of small devices. It eliminates many of the finer details of IoT systems, and
conflicts, through consolidating into a single system and single technology for connecting and
integrating all elements.
Use Case: Smart Transportation
Rail transportation provides a viable example of the power of VPC. The problems VPC solves
relate to safety, mobility, efficiency, and service improvement:
 Rail applications use their own purpose-built networks, and suffer from interoperability
issues; for example, trackside personnel cannot always communicate with local police
due to different technologies.

 Determining if passengers need extra time to board remains a mostly manual task.
 Data updates, like schedules, remain manual.
 Each piece of equipment, e.g., a surveillance camera, requires its own network and power
source.

VPC improves service by introducing direct communication over a standard network, more and
automated monitoring, automatic data updates through smart signs, and native IP networks for
all devices along with PoE (Power over Ethernet) technology. This results in passengers who feel
safer, and enjoy a better quality service.

The Salesforce IoT Cloud is a platform for storing and processing IoT data. It uses the Thunder
engine for scalable, real-time event processing. Its collection of application development
components, known as Lightning, powers its applications. It gathers data from devices, websites,
applications, customers, and partners to trigger actions for real-time responses.
Salesforce, a CRM leader, decided to enter this space due to the need to remain competitive in
the coming era. The IoT cloud adds to Salesforce by expanding its reach, and the depth of its
analytics.
Salesforce combined with IoT delivers dramatically improved customer service with tighter
integration and responses to real-time events; for example, adjustments in wind turbines could
trigger automatic rebooking of delayed/canceled connecting flights before airline passengers
land.
Electric Imp
The Electric Imp platform is Salesforce's recommended method for quickly connecting devices
to the cloud. You develop applications through the Squirrel language; a high level, OO,
lightweight scripting language. Applications consist of two modules: the device module, which
runs on the device; and the agent module, which runs in the Electric Imp cloud. The platform
ensures secure communication between the modules, and you send devices messages with a
simple call:
agent.send("nameOfmessage", data);
Listen for messages on the agent with the following code:
device.on("nameOfmessage", function(data) {
//Data operations
});
Beyond these basic tasks, coding for device interaction, monitoring, and response resembles
standard web application development, and uses a simple, easy-to-learn syntax.

GE (General Electric) Predix is a software platform for data collection from industrial instruments.
It provides a cloud-based PaaS (platform as a service), which enables industrial-grade analytics
for operations optimization and performance management. It connects data, individuals, and
equipment in a standard way.
Predix was designed to target factories, and give their ecosystems the same simple and
productive function as operating systems that transformed mobile phones. It began as a tool for
General Electric's internal IoT, specifically created to monitor products sold.
Ge Predix Partnered with Microsoft Azure
Microsoft's Azure is a cloud computing platform and supporting infrastructure. It provides PaaS
and IaaS, and assorted tools for building systems. Predix, recently made available on Azure,
exploits a host of extra features like AI, advanced data visualization, and natural language
technology. Microsoft plans to eventually integrate Predix with its Azure IoT suite and Cortana
Intelligence suite, and also their well-established business applications. Azure will also allow
users to build applications using Predix data. Note AWS and Oracle also support Predix.
Developer Kits
GE offers inexpensive developer kits consisting of general components and an Intel Edison
processor module. Developers have the options of a dual core board and a Raspberry Pi board.
Developers need only provide an IP address, Ethernet connection, power supply, and light
programming to set data collection.
The kit automatically establishes the necessary connection, registers with the central Predix
system, and begins transmitting environmental data from sensors. Users subscribe to
hardware/software output, and GE Digital owns and manages the hardware and software for the
user.

This kit replaces the awkward and involved assemblies of simulations and testing environments.
In other simulations, developers typically use a large set of software (one for each device), and
specific configurations for each connection. They also program the monitoring of each device,
which can sometimes take hours. The kit reduces much of the time spent performing these tasks
from hours to only minutes.
The Predix developer kit
The kit also includes software components for designing an IoT application that partners with
Predix services. GE plans to release other versions of the kit for different applications.

Eclipse IoT is an ecosystem of entities (industry and academia) working together to create a
foundation for IoT based exclusively on open source technologies. Their focus remains in the
areas of producing open source implementations of IoT standard technology; creating open
source frameworks and services for utilization in IoT solutions; and developing tools for IoT
developers.
Smarthome Project
SmartHome is one of Eclipse IoT's major services. It aims to create a framework for building
smart home solutions, and its focus remains heterogeneous environments, meaning assorted
protocols and standards integration.
SmartHome provides uniform device and information access to facilitate interaction between
devices. It consists of OSGi bundles capable of deployment in an OSGi runtime, with OSGi
services defined as extension points.
OSGi bundles are Java class groups and other resources, which also include detailed manifest
files. The manifest contains information on file contents, services needed to enhance class
behavior, and the nature of the aggregate as a component. Review an example of a manifest
below:
Bundle-Name: Hi Everyone // Bundle Name
Bundle-SymbolicName: xyz.xyz.hievery1 // Header specifying an identifier
Bundle-Description: A Hi Everyone bundle // Functionality description
Bundle-ManifestVersion: 2 // OSGi specification

Contiki is an operating system for IoT that specifically targets small IoT devices with limited
memory, power, bandwidth, and processing power. It uses a minimalist design while still packing
the common tools of modern operating systems. It provides functionality for management of
programs, processes, resources, memory, and communication.
It owes its popularity to being very lightweight (by modern standards), mature, and flexible.
Many academics, organization researchers, and professionals consider it a go-to OS. Contiki only
requires a few kilobytes to run, and within a space of under 30KB, it fits its entire operating
system: a web browser, web server, calculator, shell, telnet client and daemon, email client, vnc
viewer, and ftp. It borrows from operating systems and development strategies from decades
ago, which easily exploited equally small space.
Contiki Communication
Contiki supports standard protocols and recent enabling protocols for IoT:
 uIP (for IPv4) – This TCP/IP implementation supports 8-bit and 16-bit microcontrollers.
 uIPv6 (for IPv6) – This is a fully compliant IPv6 extension to uIP.
 Rime – This alternative stack provides a solution when IPv4 or IPv6 prove prohibitive. It
offers a set of primitives for low-power systems.
 6LoWPAN – This stands for IPv6 over low-power wireless personal area networks. It
provides compression technology to support the low data rate wireless needed by devices
with limited resources.
 RPL – This distance vector IPv6 protocol for LLNs (low-power and lossy networks) allows
the best possible path to be found in a complex network of devices with varied capability.
 CoAP – This protocol supports communication for simple devices, typically devices
requiring heavy remote supervision.

Dynamic Module Loading
Dynamic module loading and linking at run-time supports environments in which application
behavior changes after deployment. Contiki's module loader loads, relocates, and links ELF files.
The Cooja Network Simulator
Cooja, the Contiki network simulator, spawns an actual compiled and working Contiki system
controlled by Cooja.
Using Cooja proves simple. Simply create a new mote type by selecting the Motes menu and
Add Motes > Create New Mote Type. In the dialog that appears, you choose a name for the
mote, select its firmware, and test its compilation.
After creation, add motes by clicking Create. A new mote type will appear to which you can
attach nodes. The final step requires saving your simulation file for future use.

Internet of Things
44
Every connected device creates opportunities for attackers. These vulnerabilities are broad, even
for a single small device. The risks posed include data transfer, device access, malfunctioning
devices, and always-on/always-connected devices.
The main challenges in security remain the security limitations associated with producing low-
cost devices, and the growing number of devices which creates more opportunities for attacks.
Security Spectrum
The definition of a secured device spans from the most simple measures to sophisticated designs.
Security should be thought of as a spectrum of vulnerability which changes over time as threats
evolve.
Security must be assessed based on user needs and implementation. Users must recognize the
impact of security measures because poorly designed security creates more problems than it
solves.
Example: A German report revealed hackers compromised the security system of a steel mill.
They disrupted the control systems, which prevented a blast furnace from being shut down
properly, resulting in massive damage. Therefore, users must understand the impact of an attack
before deciding on appropriate protection.
23. IoT − Security

Internet of Things
45
Challenges
Beyond costs and the ubiquity of devices, other security issues plague IoT:
 Unpredictable Behavior – The sheer volume of deployed devices and their long list of
enabling technologies means their behavior in the field can be unpredictable. A specific
system may be well designed and within administration control, but there are no
guarantees about how it will interact with others.
 Device Similarity – IoT devices are fairly uniform. They utilize the same connection
technology and components. If one system or device suffers from a vulnerability, many
more have the same issue.
 Problematic Deployment – One of the main goals of IoT remains to place advanced
networks and analytics where they previously could not go. Unfortunately, this creates
the problem of physically securing the devices in these strange or easily accessed places.
 Long Device Life and Expired Support – One of the benefits of IoT devices is
longevity, however, that long life also means they may outlive their device support.
Compare this to traditional systems which typically have support and upgrades long after
many have stopped using them. Orphaned devices and abandonware lack the same
security hardening of other systems due to the evolution of technology over time.
 No Upgrade Support – Many IoT devices, like many mobile and small devices, are not
designed to allow upgrades or any modifications. Others offer inconvenient upgrades,
which many owners ignore, or fail to notice.
 Poor or No Transparency – Many IoT devices fail to provide transparency with regard
to their functionality. Users cannot observe or access their processes, and are left to
assume how devices behave. They have no control over unwanted functions or data
collection; furthermore, when a manufacturer updates the device, it may bring more
unwanted functions.
 No Alerts – Another goal of IoT remains to provide its incredible functionality without
being obtrusive. This introduces the problem of user awareness. Users do not monitor
the devices or know when something goes wrong. Security breaches can persist over long
periods without detection.

Internet of Things
46
IoT devices collect data about their environment, which includes people. These benefits introduce
heavy risk. The data itself does not present the danger, however, its depth does. The highly
detailed data collection paints a very clear picture of an individual, giving criminals all the
information they need to take advantage of someone.
People may also not be aware of the level of privacy; for example, entertainment devices may
gather A/V data, or “watch” a consumer, and share intimate information. The demand and price
for this data exacerbates the issue considering the number and diversity of parties interested in
sensitive data.
Problems specific to IoT technology lead to many of its privacy issues, which primarily stem from
the user's inability to establish and control privacy:
Consent
The traditional model for “notice and consent” within connected systems generally enforces
existing privacy protections. It allows users to interact with privacy mechanisms, and set
preferences typically through accepting an agreement or limiting actions. Many IoT devices have
no such accommodations. Users not only have no control, but they are also not afforded any
transparency regarding device activities.
The Right to be Left Alone
Users have normal expectations for privacy in certain situations. This comes from the commonly
accepted idea of public and private spaces; for example, individuals are not surprised by
surveillance cameras in commercial spaces, however, they do not expect them in their personal
vehicle. IoT devices challenge these norms people recognize as the “right to be left alone.” Even
in public spaces, IoT creeps beyond the limits of expected privacy due to its power.
Indistinguishable Data
IoT deploys in a wide variety of ways. Much of IoT implementation remains group targeted rather
than personal. Even if users give IoT devices consent for each action, not every system can
reasonably process every set of preferences; for example, small devices in a complex assembly
cannot honor the requests of tens of thousands of users they encounter for mere seconds.
Granularity
Modern big data poses a substantial threat to privacy, but IoT compounds the issue with its scale
and intimacy. It goes not only where passive systems cannot, but it collects data everywhere.
This supports creation of highly detailed profiles which facilitate discrimination and expose
individuals to physical, financial, and reputation harm.
Comfort
The growth of IoT normalizes it. Users become comfortable with what they perceive as safe
technology. IoT also lacks the transparency that warns users in traditional connected systems;
consequently, many act without any consideration for the potential consequences.
24. IoT − Identity Protection

Internet of Things
47
The security flaws of IoT and its ability to perform certain tasks open the door to any associated
liability. The three main areas of concern are device malfunction, attacks, and data theft. These
issues can result in a wide variety of damages.
Device Malfunction
IoT introduces a deeper level of automation which can have control over critical systems, and
systems impacting life and property. When these systems fail or malfunction, they can cause
substantial damage; for example, if an IoT furnace control system experiences a glitch, it may
fail in an unoccupied home and cause frozen pipes and water damage. This forces organizations
to create measures against it.
This smart thermostat allows attackers to gain remote access, and breach the
rest of the network.
Cyber Attacks
IoT devices expose an entire network and anything directly impacted to the risk of attacks.
Though those connections deliver powerful integration and productivity, they also create the
perfect opportunity for mayhem like a hacked stove or fire safety sprinkler system. The best
measures against this address the most vulnerable points, and provide custom protections such
as monitoring and access privileges.
25. IoT − Liability

Internet of Things
48
Some of the most effective measures against attacks prove simple:
 Built-in Security – Individuals and organizations should seek hardened devices,
meaning those with security integrated in the hardware and firmware.
 Encryption – This must be implemented by the manufacturer and through user systems.
 Risk Analysis – Organizations and individuals must analyze possible threats in designing
their systems or choosing them.
 Authorization – Devices, whenever possible, must be subject to privilege policies and
access methods.
Bitdefender BOX secures all connected devices in the home.
Data Theft
Data, IoT's strength and weakness, proves irresistible to many. These individuals have a number
of reasons for their interest: the value of personal data to marketing/advertising, identity theft,
framing individuals for crimes, stalking, and a bizarre sense of satisfaction. Measures used to
fight attacks are also effective in managing this threat.
