Exploiting friendship relations for efficient routing in mobile
Download as pptx, pdf1 like547 views
The document presents a proposed algorithm for routing messages in delay tolerant networks (DTNs) like mobile social networks. It evaluates a new social pressures metric (SPM) to detect the quality of friendships between nodes for determining the best routing paths. Prior work on multicopy, single-copy, and erasure-coding routing approaches in DTNs is reviewed. The proposed algorithm routes messages along paths containing nodes in the destination's friendship communities. Simulations show it performs better than three previous benchmark algorithms in terms of delivery ratio, cost, and efficiency.

S1240068 presentation
S1240068 presentationKuriharaYuta1 This document proposes a heuristic algorithm for allocating users to subchannels in a large-scale non-orthogonal multiple access (NOMA) system. It uses a genetic algorithm approach where individuals represent possible user allocations, and are evaluated based on throughput. The algorithm randomly assigns initial user distances and allocations, then uses crossover to generate new allocations. Evaluation shows that throughput converges after a number of generations, and increasing the number of users increases both generations needed for convergence and execution time. Future work could use parallel processing to reduce execution time for large input scales.

An efficient hybrid peer to-peersystemfordistributeddatasharingambitlick The document proposes a hybrid peer-to-peer system that combines the advantages of structured and unstructured networks. It consists of two parts: 1) a structured core network that forms the backbone and provides efficient data lookup; 2) multiple unstructured networks attached to each core node, allowing flexible peer joining/leaving. This two-tier design decouples efficiency and flexibility. Simulation results show the hybrid system balances these properties better than single-approach networks.

Word sense disambiguation and lexical chains construction using wordnet
Word sense disambiguation and lexical chains construction using wordnetUniversity Politehnica Bucharest Word sense disambiguation is an essential, yet a very difficult task in natural language processing. While several other NLP tasks, such as POS tagging, can provide more than fairly good results (highly accurate, with almost 100% rate of successfully labeled words), disambiguation is far from achieving such performances. However, we will demonstrate the need of word sense disambiguation in computing the lexical chains on a special kind of text (chats) using a WordNet-based approach. In addition, we will try to identify the bottlenecks (mostly in respect to accuracy) in such an approach and provide possible improvements

It begins by stating that opportunistic networks have unpredictable node contacts and rarely have complete end-to-end paths. It then discusses how modified TCP protocols are ineffective for these networks and they require different approaches than intermittently connected networks. The document surveys proposals for transfer reliability using hop-by-hop custody transfer and end-to-end receipts. It also categorizes storage congestion control based on single or multiple message copies. It identifies open research issues including replication management and drop policies for multiple copies.

Jamming aware traffic allocation for multiple-path routing using portfolio se...Saad Bare Multiple-path source routing protocols allow a data source node to distribute the total traffic among available paths. we consider the problem of jamming-aware source routing in which the source node performs traffic allocation based on empirical jamming statistics at individual network nodes. We formulate this traffic allocation as a lossy network flow optimization problem using portfolio selection theory from financial statistics. We show that in multisource networks, this centralized optimization problem can be solved using a distributed algorithm based on decomposition in network utility maximization (NUM). We demonstrate the network's ability to estimate the impact of jamming and incorporate these estimates into the traffic allocation problem. Finally, we simulate the achievable throughput using our proposed traffic allocation method in several scenarios.

Behavioral malware detection in delay tolerant network
Behavioral malware detection in delay tolerant networkBittu Roy This document proposes a system for detecting behavioral malware in delay tolerant networks. It presents a general behavioral characterization of proximity malware based on a naive Bayesian model. This model has been successfully used to detect malware in non-DTN settings. The system addresses challenges in extending this model to DTNs, including having insufficient evidence due to limited node contact and the risk of collecting evidence from infected nodes. It proposes techniques like look-ahead and adaptive look-ahead to balance these risks.

Providing direct communications among wireless devices within the coverage area of a cellular system can enhance coverage, spectral efficiency, and energy efficiency. However, device-to-device (D2D) communications also create new interference in cellular systems. Cognitive radio (CR) technology can help detect and exploit underutilized spectrum for D2D communications in a mixed overlay-underlay spectrum sharing approach. Analysis reveals the maximum allowable device density given a collision probability constraint and shows pushing some devices to receiving mode can preserve connectivity and keep isolation probability low. Upper bounds on cellular coverage probability are obtained incorporating load-based power allocation. Finally, implementation issues are discussed.

An Opportunistic AODV Routing Scheme : A Cognitive Mobile Agents Approach
An Opportunistic AODV Routing Scheme : A Cognitive Mobile Agents Approachijasuc In Manet’s Dynamics and Robustness are the key features of the nodes and are governed by several routing protocols such as AODV, DSR and so on. However in the network the growing resource demand leads to resource scarcity. The Node Mobility often leads to the link breakages and high routing overhead
decreasing the stability and reliability of the network connectivity. In this context, the paper proposes a novel opportunistic AODV routing scheme which implements a cognitive agent based intelligent technique to set up a stable connectivity over the Manet. The Scheme computes the routing metric (rf) based on the collaboration sensitivity levels of the nodes obtained based through the knowledge-based decision. This Routing Metric is subsequently used to set up the stable path for network connectivity. Thus minimizes the route overhead and increases the stability of the path. The Performance evaluation is conducted in comparison with the AODV and sleep AODV routing protocol and validated.

F0313539
F0313539iosrjournals This document proposes and evaluates a new routing protocol called Conditional Shortest Path Routing (CSPR) for delay tolerant networks. CSPR uses a new metric called conditional intermeeting time to determine link costs, which measures the average time between two nodes meeting given that one node previously met a third node. Through simulations using real mobility traces, CSPR is shown to achieve higher delivery rates and lower end-to-end delays than existing shortest path routing protocols that use conventional intermeeting times as link costs. The conditional intermeeting time better captures link characteristics and allows for more effective forwarding decisions in routing messages.

COMMUNITY DETECTION USING INTER CONTACT TIME AND SOCIAL CHARACTERISTICS BASED...ijasuc Delay Tolerant Networks (DTNs) where the node connectivity is opportunistic and end-to-end path between
any pair of source and destination is not guaranteed most of the time. Hence the messages are transferred
from source to destination via intermediate nodes on hop to hop basis using store-carry-forward paradigm.
Due to quick advancement in hand held devices such as smart phone and laptop with support of wireless
communication interface carried by human being, it is possible in coming days to use DTNs for message
dissemination without setting up infrastructure. The routing task becomes challenging in DTNs due to
intermittent network connectivity and the connection opportunity arises only when node comes in
transmission range of each other. The performance of the routing protocols depend on the selection of
appropriate relay node which can deliver the message to final destination in case of source and destination
do not meet at all. Many social characteristics are exhibited by the human being like friendship,
community, similarity and centrality which can be exploited by the routing protocol in order to take the
forwarding decisions. Literature shows that by using these characteristics, the performance of DTN routing
protocols have been improved in terms of delivery probability. The existing routing schemes used
community detection using aggregated contact duration and contact frequency which does not change over
the time period. We propose community detection through Inter Contact Time (ICT) between node pair
using power law distribution where the members of community are added and removed dynamically. We
also considered single copy of each message in entire network to reduce the network overhead. The
proposed routing protocol named Social Based Single Copy Routing (SBSCR) selects the suitable relay
node from the community members only based on the social metrics such as similarity and friendship
together. ICTs show power law nature in human mobility which is used to detect the community structure at
each node. A node maintains its own community and social metrics such as similarity and friendship with
other nodes. Whenever node has to select the relay node then it selects from its community with higher
value of social metric. The simulations are conducted using ONE simulator on the real traces of campus
and conference environments. SBSCR is compared with existing schemes and results show that it
outperforms in terms of delivery probability and delivery delay with comparable overhead ratio.

Content Sharing over Smartphone-Based Delay-Tolerant Networks
Content Sharing over Smartphone-Based Delay-Tolerant NetworksIJERA Editor With the growing number of smartphone end users, peer-to-peer ad hoc content giving is likely to occur often. Thus, new articles sharing mechanisms must be developed since traditional information delivery schemes will not be efficient with regard to content sharing due to the sporadic connectivity between smartphones on the market. To obtain data delivery such challenging environments, researchers include proposed the employment of store-carry-forward methodologies, in which a node stores a communication and holds it until a forwarding prospect arises through an encounter together with other nodes. Most past works in this field have dedicated to the conjecture of whether two nodes could encounter the other, without thinking about the place and also time from the encounter. In this particular paper, we propose to her discover-predict-deliver as a possible efficient articles sharing scheme for delay-tolerant touch screen phone networks. In this proposed scheme, contents are usually shared while using the mobility information of people. Specifically, our strategy employs the mobility understanding algorithm to spot places inside your own home and outdoor.

Content Sharing over Smartphone-Based Delay-Tolerant Networks
Content Sharing over Smartphone-Based Delay-Tolerant NetworksIJERA Editor With the growing number of smartphone end users, peer-to-peer ad hoc content giving is likely to occur often. Thus, new articles sharing mechanisms must be developed since traditional information delivery schemes will not be efficient with regard to content sharing due to the sporadic connectivity between smartphones on the market. To obtain data delivery such challenging environments, researchers include proposed the employment of store-carry-forward methodologies, in which a node stores a communication and holds it until a forwarding prospect arises through an encounter together with other nodes. Most past works in this field have dedicated to the conjecture of whether two nodes could encounter the other, without thinking about the place and also time from the encounter. In this particular paper, we propose to her discover-predict-deliver as a possible efficient articles sharing scheme for delay-tolerant touch screen phone networks. In this proposed scheme, contents are usually shared while using the mobility information of people. Specifically, our strategy employs the mobility understanding algorithm to spot places inside your own home and outdoor.

An Experimental Result of Conditional Shortest Path Routing In Delay Toleran...IOSR Journals This document discusses an experimental study of conditional shortest path routing in delay tolerant networks. It proposes a new metric called conditional intermeeting time, which measures the average time between two nodes meeting given that one node has already met a third node. It then presents a conditional shortest path routing protocol that uses conditional intermeeting times rather than standard intermeeting times to determine path costs. Simulation results show this approach achieves higher delivery rates and lower delays compared to existing shortest path routing protocols for delay tolerant networks.

The document proposes methods for discovering communities in social networks using content and interactions by modeling communities based on discussed topics and social connections between users. This allows discovering both user interests and popular topics within each community.
2. Bayesian models are used to extract latent communities from the network, assuming community relationships depend on user interests in topics and their links. Different models are proposed to handle different network structures like broadcast vs conversation networks.
3. The models aim to utilize both content and link information to discover communities in incomplete social networks with missing link information. A distance metric is learned using observed links and used for hierarchical clustering.

An Extensive Literature Review of Various Routing Protocols in Delay Tolerant...IRJET Journal This document summarizes an extensive literature review on routing protocols in delay tolerant networks (DTNs). It begins by defining DTNs as wireless networks with intermittent connectivity where nodes use a store-carry-forward mechanism. Common routing protocols for DTNs like epidemic, spray and wait, and prophet are described. The document then reviews several papers that propose and evaluate new routing algorithms or improvements for DTNs, analyzing metrics like delivery ratio, overhead, and latency. Key factors considered include node contact histories, social characteristics, energy constraints, and message prioritization. Finally, it suggests the contact duration between nodes could be an important parameter to further optimize routing in DTNs.

It discusses how selecting routes with fewer transmissions and retransmissions can improve throughput and delay. Existing approaches optimize either cost or number of hops but not both. The paper proposes a new routing metric and algorithm to find the optimal cost path with the optimal or minimum number of hops, in order to balance throughput, delay, and power consumption for wireless data transmission. It provides an example to illustrate the concept and compares different path options.
AN EFFICIENT ROUTING PROTOCOL FOR DELAY TOLERANT NETWORKS (DTNs)
AN EFFICIENT ROUTING PROTOCOL FOR DELAY TOLERANT NETWORKS (DTNs)cscpconf Delay-Tolerant Networks are those which lacks continuous communications among mobile
nodes . Distributed clustering scheme and cluster-based routing protocol are used for DelayTolerant
Mobile Networks (DTMNs). The basic idea is to distributive group mobile nodes with
similar mobility pattern into a cluster, which can then interchangeably share their resources for
overhead reduction and load balancing, aiming to achieve efficient and scalable routing in DTMN. Load balancing is carried out in two ways, Intra cluster load balancing and Inter cluster load balancing. The Convergence and stability become major challenges in distributed clustering in DTMN. An efficient routing protocol will be provided for the delay tolerant networks through which the stability of the network is maintained .Based on nodal contact probabilities, a set of functions including Sync(), Leave(), and Join() are devised for cluster formation and gateway selection. Finally, the gateway nodes exchange network information and perform routing

It develops a finite-state absorbing Markov chain framework to model the message delivery process. Based on this, it derives closed-form expressions for message delivery probability under different message lifetimes and sizes. The key findings are that two-hop relay with erasure coding can improve delivery probability compared to traditional routing, and the probability varies based on message parameters and node density.

iaetsd Survey on cooperative relay based data transmissionIaetsd Iaetsd The document discusses cooperative relay based data transmission and proposes a system to select the most energy efficient relay node for a source node to transmit data through. It analyzes different cooperative relaying techniques like amplify-and-forward, decode-and-forward, and compress-and-forward. The proposed system aims to minimize the source node's cost for cooperation by selecting the relay node that provides the highest energy efficiency. This allows high data transmission over long distances with improved energy efficiency compared to direct transmission without a relay.

infrastructure less environment to establish a data transmission between nodes within the network. A routing
protocol is used to discover routes between nodes. In this paper, we study the three existing routing protocols
namely AODV, DSDV and DSR to analyze theirperformance based on set of parameters.AODV and DSR
deliver almost all the packets compared to DSDV. Hence we try to modify the AODVprotocol and use in the
cooperative transmission.
In this paper, we study the cooperative transmission at the network layer and cooperative diversity at the
physical layer as a joint optimization of the transmission power in a Mobile Ad-Hoc Network (MANET) with
static channel. However due to variable wireless channels static routing is suboptimal. Proposed protocol
proactively selects forwarding nodes that work cooperatively forwarding the packet towards the destination.
Cooperative transmission side diversity helps in reducing interference. Diversity can be achieved at the physical
layer by coordinating the multiple nodes. Nodes are equipped with Omni-directional antenna and take the
advantages of transmission side diversity to achieve energy saving, under the assumption that channel gains are
available at the transmitters.
The proposed Opportunistic Minimum Cost Cooperative Transmission Shortest Path (OMCTSP) algorithms
select the best optimum route with minimum cost in terms of energy, number of hops, available bandwidth, link
quality (SNR) and outage probability. As the network becomes larger, finding optimal routes becomes
computationally intractable as the complexity of the dynamic programming (DP) approach increases as o (22n)
where n is the number of nodes in the networks. Hence we develop two suboptimal algorithms have complexity

Route Stability in Mobile Ad-Hoc Networks
Route Stability in Mobile Ad-Hoc Networksarpublication A Mobile Ad Hoc Network (MANET) is a wireless network consisting of mobile nodes, which can communicate with each other without any infrastructure support. In these networks, nodes typically cooperate with each other, by forwarding packets for nodes which are not in the communication range of the source node. A fundamental issue arising in mobile ad-hoc networks (MANETs) is the selection of the optimal path between any two nodes. A method that has been advocated to improve routing efficiency is to select the most stable path so as to reduce the latency and the overhead due to route reconstruction. In this work we study the stability of a routing path, which is subject to link failures caused by node mobility, and we consider as metrics of interest the duration and the availability of a path. Moreover, using the results on path duration and availability, we show how to determine the optimal path in terms of route stability, under the Random Direction mobility models.
Opportunistic Routing in Delay Tolerant Network with Different Routing Algorithm
Opportunistic Routing in Delay Tolerant Network with Different Routing AlgorithmInternational Journal of Science and Research (IJSR) Present new mechanisms for modelling multiple interfaces on a node, support for interference-limited links and a frame-work for modelling complex applications running on the nodes. Furthermore, provide an overview of concrete use cases where the simulator has been successfully exploited to study a variety of aspects related to opportunistic, message-based communications. Node movement is implemented by movement models. These are either synthetic models or existing movement traces. Connectivity between the nodes is based on their location, communication range and the bit-rate. The routing function is implemented by routing modules that decide which messages to forward over existing contacts. Finally, the messages themselves are generated either through event generators that generate random traffic between the nodes, or through applications that generate traffic based on application interactions. The main functions of the simulator are the modelling of node movement, inter-node contacts using various interfaces, routing, message handling and application interactions. Result collection and analysis are done through visualization, reports and post-processing tools.

Espresso PD Official MP_eng Version.pptx
Espresso PD Official MP_eng Version.pptxNingChacha1 Cosmetic standards in manufacturing play a crucial role in ensuring the visual quality of products meets customer expectations while maintaining functional integrity. In industries such as electronics, automotive, and consumer goods, cosmetic defects—though often non-functional—can impact brand perception, product desirability, and customer satisfaction.
### **Introduction to Cosmetic Standards in Manufacturing**
Cosmetic standards refer to the guidelines set by manufacturers to evaluate the appearance of a product. These guidelines define acceptable and unacceptable visual defects, ensuring products present a clean, professional look. While minor imperfections may be permissible, consistent and visible defects can lead to customer complaints or reduced marketability.
### **Key Cosmetic Defects in Manufacturing**
Manufacturing processes can introduce various cosmetic defects, including:
- **Scratches and Scuffs**: Surface-level marks that occur during handling, assembly, or packaging.
- **Dents and Deformations**: Physical damage to materials due to improper handling or tooling issues.
- **Color Variations**: Differences in shading or texture due to material inconsistencies or environmental factors during production.
- **Molding Defects**: Injection molding processes can introduce flow lines, sink marks, or flash, affecting the visual quality of plastic components.
- **Print and Label Imperfections**: Misaligned text, smudging, or incomplete printing can impact branding and identification.
- **Paint or Coating Defects**: Issues such as peeling, chipping, or uneven application affecting surface finish.
- **Contaminations and Foreign Material**: Dust, hair, or other particles embedded in the product can be perceived as poor workmanship.
### **Defining Cosmetic Acceptance Criteria**
Manufacturers typically establish cosmetic acceptance criteria based on industry standards, customer expectations, and internal quality requirements. These criteria specify:
- **Defect Classification**: Minor, major, or critical defects based on impact on functionality and aesthetics.
- **Inspection Methods**: Visual inspection under controlled lighting conditions and specific angles.
- **Measurement Tools**: Rulers, calipers, or digital inspection systems for consistency in defect evaluation.
- **Pass/Fail Guidelines**: Clear thresholds for acceptable and non-acceptable defects.
### **Inspection and Quality Control Methods**
To enforce cosmetic standards, manufacturers implement stringent inspection processes, including:
- **Automated Vision Systems**: Using AI-powered cameras to detect surface irregularities.
- **Manual Inspection**: Trained personnel evaluating each unit based on predefined standards.
- **Sampling Plans**: Statistical methods such as AQL (Acceptable Quality Limit) to ensure representative evaluation.
- **Defect Tagging and Sorting**: Classifying defective units for rework, scrapping, or customer review.

DeFAIMint | 🤖Mint to DeFAI. Vibe Trading as NFTKyohei Ito DeFAI Mint: Vive Trading as NFT.
Welcome to the future of crypto investing — radically simplified.
"DeFAI Mint" is a new frontier in the intersection of DeFi and AI.
At its core lies a simple idea: what if _minting one NFT_ could replace everything else? No tokens to pick.
No dashboards to manage. No wallets to configure.
Just one action — mint — and your belief becomes an AI-powered investing agent.
---
In a market where over 140,000 tokens launch daily, and only experts can keep up with the volatility.
DeFAI Mint offers a new paradigm: "Vibe Trading".
You don’t need technical knowledge.
You don’t need strategy.
You just need conviction.
Each DeFAI NFT carries a belief — political, philosophical, or protocol-based.
When you mint, your NFT becomes a fully autonomous AI agent:
- It owns its own wallet
- It signs and sends transactions
- It trades across chains, aligned with your chosen thesis
This is "belief-driven automation". Built to be safe. Built to be effortless.
- Your trade budget is fixed at mint
- Every NFT wallet is isolated — no exposure beyond your mint

- 3. INTRODUCTION Delay tolerant network Real life examples -MSNs Opportunistic routing of messages Enable nodes to make right forwarding decisions while routing messages
- 4. Cont’d…. The relationship defining the frequency and duration of the connectivity between nodes has to be analyzed to route messages efficiently Ex: high school network A new metric that detects the quality of friendship between the nodes either Directly Indirectly
- 5. RELATED WORK General DTN Routing Algorithms Multicopy based Single-copy based Erasure-coding based
- 6. Multicopy based Exchange of messages The drawback is: Excessive usage of bandwidth Buffer space Energy due to spreading of copies
- 7. Single copy based Based on movement of the nodes. In Max-Prop prioritization of the schedule of packets that will be transmitted to other nodes or that will be dropped from the buffer
- 8. Erasure-coding based The message is divided into large set of blocks Advantage Robustness to failures Increase the delivery rate
- 9. Contd….. Social-Based Routing for MSNs Daly and Haahr use both social similarity and egocentric betweenness metric to increase routing performance. Each node is assumed to have two rankings: global local.
- 10. Analysis of Node Relation
- 11. Friendship Community Formation Used in forwarding of messages. Three behavioral features of close friendships: high frequency longevity regularity A new metric, social pressures metric (SPM) to accurately detect the quality of friendship. The link quality wi,j between each pair of nodes(i, j), is defined as wi,j = 1/SPMi,j
- 12. ‘what would be the average delivery delay of node i’s continuously generated messages if they followed the path <i,j,k>’?
- 13. Handling periodic variation in node Relation
- 14. EVALUATION Three metrics: Message delivery ratio Average cost Routing efficiency
- 16. CONCLUSION New metric to detect friendship-based node relations accurately. Presented a new routing algorithm in which a node forwards its messages to those nodes that contain the destination node in their friendship communities. Evaluated the proposed algorithm through simulations. Algorithm performs better than three benchmark algorithms proposed previously.
