Jammer Selection In Heterogeneous Networks With Full-Duplex Users
2016 IEEE Global Communications Conference (GLOBECOM)(2016)
摘要
In this paper, we investigate the downlink physical layer security for heterogeneous networks (HetNets), where the confidential message can be eavesdropped by multiple eavesdroppers. To enhance the secrecy performance, we introduce friendly jammers and full-duplex users in our model. We propose a jammer selection scheme, where the jammers' interference power on the scheduled users below a threshold are selected to transmit independent artificial noise to confuse the passive eavesdroppers. Furthermore, the scheduled users try to jam the eavesdroppers using full-duplex and artificial noise. Using the tools of stochastic geometry, we derive the theoretical analyses of user connection probability and secrecy probability. In particular, the locations of selected jammers are modeled by a Poisson hole process (PHP) instead of more popular homogeneous Poisson point process (PPP). Our analytical results show a good agreement with the simulations. The ergodic secrecy rate in our scheme outperforms that in the traditional HetNets.
