Role of LwM2M Devices in IoT

An Overview

• Open Mobile Alliance (OMA) protocol• Designed for Machine to Machine or IoT device management• Communication between LwM2M Server to LwM2M client• Developed for sensor networks • Managing lightweight and low power constrained devices• Based on representational state transfer (REST)• Created for remote management of M2M devices• Enable various IoT services

Supported and Endorsed by

- Secured data transfer – Constrained Application Protocol (CoAP)- IPSO- Based on working group standards from IETF (Internet Engineering task force)- Supported by Eclipse Foundation. Implemented:

Leshan – JavaWakaama – C

OMA Lightweight M2M is designed to:

• Provide Device Management functionality over sensor or cellular

networks

• Transfer service data from the network to devices

• Extend to meet the requirements of most any application

Role of LwM2M Devices in IoT

Designed to create the following opportunities and business benefits for the M2Mindustry:

• Reduce the degree of fragmentation • Enabling more plug-and-play solutions• Act as an enabler to grow the M2M market in various segments ranging from

smart cityEnergy management Location tracking. Low cost to enable sustainable business models.

Role LwM2M Devices in IoT

• Improve time-to-market and the manageability of devices• Lead to a decoupling of M2M appliances and server-side platforms, thereby enabling

independent innovation of M2M devices and platforms.

• Growing the number of interoperable M2M connected devices to provide more choice for M2M

customers regarding M2M devices and their management platforms.

Operations to be impacted by M2M and IoT

deployments

• M2M deployments will get more sophisticated – and deliver greater ROI

• IoT will become vital to the customer experience

• There will be a new focus on connecting the ‘things’ that matter

Advantages of Implementation of LwM2M applications

Implementation of LwM2M protocol on IoT devices will:

• Reduce the cost

• Save the time

• Reduce risk

• Unlocks the door for new innovations.
