LWM2M: The Future of IoT

The IoT industry continues to evolve at a rapid rate and with it, the standards and protocols used to develop the technology. One of the leading IoT protocols has been created and endorsed by the Open Mobile Alliance (OMA) is the Lightweight Machine-to-Machine (LWM2M). This technical specification is principly a device management protocol, but it should be designed to be able to extend to meet the requirements of applications. LWM2M is not restricted to device management, it should be able transfer service / application data. It provides a choice for the M2M Service Provider to deploy a M2M system to provide service to the M2M user.

The aim of OMA M2M is to create a new management standard for IoT. Many M2M devices have very constrained resources (bandwidth, memory), but the OMA standard looks to provide rich functionality within these constraints. The combination of traditional device management functionality with the efficiencies introduced by OMA LWM2M allows companies from a broad range of industries to truly leverage the cost savings offered by the Internet of Things.

Devices that enable the Internet of Things are often simple sensors that are deployed to help understand the environment they are within, from this data automated processes can be triggered in response to different scenarios. These devices will also have a number of challenges for device management that are addressed by OMA LWM2M, for example:

  • The protocol has a very small overhead for the messages that devices need to generate. This prevents device management from causing an undue strain on the resources available within a device.
  • The devices will be using a broad range of connectivity options, some of these are restrictive on the amount of bandwidth that can be consumed (e.g. mobile, white space) and the low overhead of the device management communications ensure that this bandwidth is used efficiently.

Beamfly’s LWM2M platform combines device management functionality with the efficiencies introduced by OMA LWM2M, allowing businesses from a broad range of industries to truly leverage the cost savings offered by the Internet of Things.
