IoT, Volume 3, Issue 1

March 2022 - 14 articles

Cover Story: The Internet of Things brings connectivity to everyday objects. These connected devices have to be managed considering their severe constraints in terms of energy, memory, processing, and communication. In this context, the OMA LWM2M protocol has been designed for remote device management, through a server usually deployed in the cloud. We propose the introduction of a LWM2M Proxy at the network edge, in between devices and servers, to improve various LWM2M procedures. Moreover, the Proxy enables the support of QoS-aware services through a set of extended functions to efficiently use resources at the edge, thus providing a reduced and more predictable end-to-end latency. We evaluate this solution both by simulation and experimentally, showing that it can thoroughly improve the performance of the system. View this paper
