Semi-Persistent Services for IoT Networks Using RESTful Approach

The paper proposes a new way to access semi-permanent services in ad-hoc and mesh networking in the context of the Internet of Things and the Internet of Services. The solution is based on address-free communication, with individual addresses of the nodes replaced by a semantic description of their functionality. The mesh network is accessible from outside using the classic RESTful approach and needs no centralized catalog to maintain at-the-moment available services. Instead, entry gateways are responsible for mapping incoming REST-compliant communication to internal mesh messaging, and the mesh nodes individually decide how to react to particular messages. Installing each new or replaced node or monitoring the node status is unnecessary. Automatic communication among the nodes is possible without human intervention, including both runtime and the registration phase. Bluetooth mesh topology network was chosen as the implementation base. Transmission in the network occurs in a broadcast mode, in which one network node sends information that is then received and interpreted by all other nodes. Selected devices equipped with alternative communication modules of a different type, in particular, connected to the home WiFi network, can be used as input/output gateways for outside communication.
