Device group management in constrained networks
María Inés Robles, Domenico D'Ambrosio, Jaime Jiménez Bolonio, Miika Komu · 2016
Internet of Things is a paradigm that defines networking of various kinds of devices that are typically constrained, e.g., by limited amount of memory. Lightweight Machine to Machine (LWM2M) is a client-server protocol for managing such constrained devices. It is based on the Constrained Application Protocol (CoAP). Group communications remain undefined in LWM2M specifications, but can be supported by, e.g., proxy-based solutions. In this paper, we describe details about group management extensions for LWM2M using such a proxy, evaluate its performance and discuss its potential benefits.
