Secrecy Enhancement by Antenna Selection and FD Communication with Randomly Located Eavesdroppers

Abstract : This paper investigates the secrecy connectivity probability for wireless networks with transmit antenna selection in the presence of randomly located eavesdroppers. Firstly, we propose an antenna selection scheme for use at the base station with a half-duplex receiver to enhance secrecy connectivity performance. Then in order to further improve the secrecy connectivity, a full-duplex (FD) receiver, which broadcasts a jamming signal while receiving the downlink message, is considered in this work. The probabilities of secrecy connectivity are given in the closed form and integral form for half-duplex and full-duplex receivers, respectively. The derived analytical results are verified by Monte Carlo simulations. The resulting analysis shows that the application of antenna selection at the transmitting base station and full-duplex communication at the receiving terminal leads to significant improvements in secrecy connectivity.
