OMA LWM2M: Breaking down the silos that limit IoT at scale

Thanks to everyone for the huge interest in the LwM2M
webinar we hosted on February 13th. The timing was excellent as
version 1.0 of the LwM2M specification was just finalized and published so we were
able to share the most recent developments with our attendees.

We often hear concerns from our partners as
they grapple with scaling out their IoT deployments, as they find that silos
within IoT have created vendor lock-in issues, stunting their potential growth.

IoT is still at an early stage and, as
often happens in other industries, there are a lot of proprietary developments.
With the Open Mobile Alliance (OMA) LightWeight Machine-to-Machine (LwM2M) and
our ARM mbed Cloud IoT device management solution, we want to open today’s
narrow IoT silos.  A device management
standard offers a number of possibilities: first, you can take a LwM2M
compliant IoT device from vendor A and connect it to a cloud provider B.
Second, you can switch from cloud provider B to cloud provider C, if you are
unhappy with the offered service. Third, you can see all the details of the
technical specification and even participate in the development of the
standard. Finally, with more companies participating in the design, testing and
implementation, the quality tends to be better, which cannot be underestimated
in context of security.

Within the mbed partner ecosystem, we share a
strong vision for the future: To securely deploy commercial IoT devices at
scale, to be harnessed by the broadest possible range of enterprises. To deliver the true potential of IoT, we
need any device, connected over any communication network, to interact securely
with any cloud application platform and be targeted by any developer.

The LwM2M protocol provides a common
standard for controlling constrained and low power devices in a network
agnostic way, securely facilitating the remote management and enablement of
devices. When implemented, it hides device and network diversity from cloud
developers, presenting a consistent RESTful interface. Built on proven IETF
standards, such as CoAP and DTLS, the LwM2M
protocol defines an extensible resource and data model for devices. All of
these features make LwM2M an ideal basis for the mbed Cloud services.


The OMA standard provides a foundation for
the following aspects of mbed Cloud:

  • Securely managing the lifecycle
    of each device in large scale IoT deployments: From manufacture, to
    bootstrapping into an active deployment, managing IoT device/service trust
    relationships and removing devices from service when necessary.
  • Collecting data from devices to
    enable their behaviors to be analyzed and quantified.
  • Sending data and control
    commands to devices.
  • Triggering and managing remote
    Firmware over-The-Air (FoTA) updates.

With the completion of version 1.0 of the
LwM2M specification, our work is not finished. We are working with the OMA
towards the upcoming testfest (see,
and will continue to help drive this
standard forward, addressing the future needs of secure IoT deployment management and prioritizing interoperability, efficiency and increased developer productivity.
