Enhancing secrecy with multi-antenna transmission in wireless ad hoc networks

Zhang, Xi; McKay, Matthew R; Zhou, Xiangyun


We study physical-layer security in wireless ad hoc networks and investigate two types of multi-antenna transmission schemes for providing secrecy enhancements. To establish secure transmission against malicious eavesdroppers, we consider the generation of artificial noise with either sectoring or beamforming. For both approaches, we provide a statistical characterization and tradeoff analysis of the outage performance of the legitimate communication and the eavesdropping links. We then...[Show more]
