A Device to Device (D2D) Spectrum Sharing Scheme for Wireless Industrial Applications

In this paper, we present a spectrum sharing scheme for Device to Device (D2D) deployments in a wireless Internet of Things (IoT) industrial environment. Interference management for this scheme relies on the relative distance between participating users or devices. The D2D links can access spectrum by sharing resources with cellular users or by using dedicated channels. The presented scheme maximises the throughput of admitted D2D links without compromising the Quality of Service (QoS) requirements of users in the network. An optimisation approach is adopted to solve the spectrum sharing problem resulting in an efficient allocation and throughput maximisation for all participating users and devices.
