Physical-Layer Security Performance Analysis of Cooperative Systems with Energy Harvesting-based Relay
Bolun Li, Tao Liang, Aiwei Sun
The rapid development and popularization of wireless communications makes communication resources even more short and communication service face even bigger security threat. To improve the security and energy and spectrum efficiency, the research is focused on the communication system, which is composed of an information transmitter, a desired receiver, an eavesdropper and a full-duplex relay, Among those the relay node with energy harvesting capability works in full-duplex mode. Via building the system as flat Rayleigh fading model, the security performance of the system is analyzed, and the theoretical expression of security outage probability acquired.Finally, Monte Carlo simulation results verify the theoretical-analysis results, and indicate the effect of various parameters on the system performance.
