Lightweight M2M protocol: Archetyping an IoT device, and deploying an upgrade architecture

Abstract

The Internet of Things (IoT) is made up of billions [1] of connected devices worldwide, with different lifecycle profiles. This engineering project explores lifecycle management solutions through the study of two IoT open-source projects, analyzing a newly published communication protocol – the Lightweight Machine-to-Machine (LwM2M) – and a multiprotocol software update project named HawkBit. As a first step, a LwM2M IoT device archetype is created, so as to explore the protocol and its functionalities, in particular the firmware update. In a second step, a firmware upgrade campaign is simulated in order to analyze the behavior and limitations of both solutions.
