OneM2M Based-Interworking Architecture for Heterogeneous Devices Interoperability in IoT

The Internet of things (IoT) fosters a hyper-connected world in which billions of devices that range from higher-grade intelligent mobile terminals to resource-constrained sensors will be connected to the Internet anytime and anywhere. Nevertheless, one of the major obstacles facing the Internet of things is the high diversity of communication capabilities (protocols, technologies and hardware) of the IoT devices. This diversity leads to a highly fragmented IoT market, where various IoT solutions have been developed independently and separately to be used in legacy deployment, which prioritize the vertical optimization instead of the horizontal. Therefore, in this research, in order to address this issue, we analyse the oneM2M specifications and propose an interworking architecture based on such specifications to support both the seamless interoperability of heterogeneous IoT devices and their integration with oneM2M ecosystem. We evaluate the feasibility of this architecture by a use case applied to under real scenario, which derives from an ongoing project.
