Security-oriented distributed access selection for D2D underlaying cellular networks
In device-to-device (D2D) underlaying cellular networks, interference generated by D2D communications can be exploited to improve secrecy rate of cellular users (CUE). The security-oriented distributed access selection algorithm is proposed, in which each D2D pair decides whether to access to radio resources according to its local channel state information without considering the locations of D2D pairs and Eve. The ergodic secrecy rate of CUE and the data rate of D2D pairs in the proposed scheme are investigated. Simulation results show that the proposed scheme can achieve an impressive secrecy performance gain.
