Abstract

D2D communication and cognitive radio are among the key technologies that can solve the bandwidth bottleneck problem of cellular networks. These technologies help to maintain necessary communication between the user devices in case of natural disasters and traffic hotspot situations. In this paper, we efficiently employ the relay selection and cooperative beamforming (CBF) strategies for D2D communication and show that the user devices can securely communicate with each other without infrastructure support. The cloud heads in our proposal act as the primary users (PUs) and the cloud members are regarded as the secondary users (SUs) or the relay nodes. To investigate the efficiency of our proposal, we define the utilities of PUs employing relay selection and CBF, considering received signal power, latency, channel gain and security. We optimize relay selection and beamforming vector by solving mixed integer non-linear problem (MINLP). Numerical results show the efficiency and robustness of our approach.
