Enhanced Support of LWM2M in Low Power and Lossy Networks

Abstract

The Internet of Things (IoT) extends the Internet connectivity into devices and everyday objects. This huge volume of connected devices needs to be managed considering the severe energy, memory, processing, and communication limitations of IoT devices and networks. OMA LightweightM2M (LWM2M) protocol is designed for remote management of constrained devices and related service enablement. In this work we propose the introduction of a LWM2M Proxy in between IoT devices and the management server, in order to control the flow of LWM2M requests sent to IoT devices over a low-power and lossy network, and therefore avoid that device and network resources get overloaded. We evaluate the proposed solution by simulation and show that it strongly improves the performance of LWM2M in terms of service delay as compared to the standard case with no Proxy.
