Trust based D2D communications for accessing services in Internet of Things

Internet of Things (IoT) is a vision of connecting everything for providing better services efficiently. IoT consists of enormous number of heterogeneous computing devices with different capabilities to provide a diverse range of services situated around the globe. Increasing number of IoT devices and availability of different services in the edge of the networks makes it inevitable to interact among devices. As a result, this open, non-homogeneous and distributed environment also breaches the integrity of secure and reliable device to device (D2D) communication. Traditional access control mechanisms are not prolific to the itinerant, decentralized and dynamic scenarios in the IoT. Trust management is a proven technology for applications like P2P, Grid, and ad hoc network. Hence, this technology can also be used to increase the user reliability in IoT. In this paper, we propose a trust based D2D communication mechanism for accessing different services to meet the growing transactions and successful operations of IoT. We also analyze the effect of adaptive trust parameters for IoT device to device communication in order to access the services.
