Interworking of Onem2M-Based IoT Systems and Heterogeneous IoT Devices

Abstract

Lack of interoperability between devices is a key aspect of IoT application development where different heterogeneous devices are intended to seamlessly interoperate. Moreover, if we focus on implementing the interaction and interconnection between devices and standard IoT platforms, the challenge is even more complex because of the inherent heterogeneity in the protocols, technologies, and data formats supported by each device. To solve this problem, we propose an interworking architecture based on the oneM2M standard through the implementation of an Interworking proxy entity (IPE) that acts as a middleware between the heterogeneous IoT devices and oneM2M-based IoT systems. The functionality of the architecture is validated through a scenario applied to port transport and logistics.
