P2PIoT: A Peer-To-Peer Communication Model for the Internet of Things

The general structure of the Internet of Things (IoT) networks is still an interesting matter for research and innovation. Common IoT uses scenarios show an undefined number of IoT instances running independently and simultaneously. In general, each IoT instance operates under a middleware that provides a set of abstractions to facilitate the integration and communication of components, acting as a mediation layer between the physical layer and the application layer. This paper proposes a model for the interoperation of different IoT instances using peer-to-peer (P2P) services providing operations to federate these instances in fixed and mobile scenarios. The proposed architecture supports services to merge and split IoT instances, as well as to move, replicate and delete IoT data, software entities, and devices's abstractions. The proposal is validated by testing a developed prototype and discussing its functionalities and performance.
