OMA LWM2M: Introduction
Background
Open Mobile Alliance (OMA)
was established in 2002
OMA LWM2M is the
evolution of the expertise
from OMA in Device
Management (DM) for
addressing the new
requirements from
constrained devices and fill
the gap between 3GPP, IETF
CoAP, ETSI and OMA-DM
Define interfaces, protocols
(SMS, CoAP) and security
support between machines
and the server/cloud
Define a Object and
Resources Data Model
(Semantic)
Leverage the expertise in
Device Management with
support for firmware
update, connectivity,
discovery, access control,
bootstrapping and remote
management
Goals
Bootstrapping: Pre-
provisioned of security
credentials (keys, tokens) ,
configuration of LWM2M
Servers IP, etc.
Registration: Register the
Client and its OMA Web
Objects in the Resource
Directory (Local or Cloud)
Management and Service:
Operational mode to read,
update, and manage
objects/resources
Information Reporting:
Observation of Resources for
events notification
Functions/Interfaces
A device can have multiple
Objects. An Object is a
collection of resources. A
resource is the atomic piece
of data (e.g., temperature
value, sampling frequency)
OMA and other SDOs 1 can
define and register Objects
Object Data Model presents
a highly efficient payload
Objects and Resources can
have multiple instances.
/{Obj. ID}/{Obj. Instance}/{Res. ID}/
Supported meta-data for
security control such as
Access Control List (ACL)
Object Data Model
1- HOP Ubiquitous is member of IPSO
Alliance & OMA Web Objects Builder.
