Optimal relay and jammers selection for enhancing security in AF relay networks
In this paper, we investigate optimal and jammers selection for enhancing security in amplify-and-forwarding (AF) relay networks. A relay is selected to deliver messages to destination working in conventional mode; two nodes are selected to operate as jammers for interfering with eavesdropper. The proposed schemes make use of the channel coefficients as weights of beamforming for jammers, designed to maximize the secrecy rate while not interfere with the destination. It is proven that zero-approaching outage probability is possible when total transmission power is very large. The improvement of the proposed selection schemes are verified by analytical and simulation results.
