The oneM2M is an international partnership project, established to aim at developing the global standard service platform for the Machine-to-Machine (M2M) as well as Internet of Thing (IoT). It promises to allow in-tegration of various communication technology and application protocol in only consolidated open system while in the market, most of M2M/IoT solution are highly vertical and proprietary. oneM2M also can be de-veloped in edge computing environment to process real-time numerous IoT devices’ data. This work pro-vides an overview of oneM2M and several actual implementation results that enable interoperating the dis-parate layer protocol and multiple technology in a simple scenario.
