Secrecy Performance of an improved Interference-aided RF Energy Harvesting scheme in Two-Way Multi-Antenna Relay Network

Abstract

This paper introduces a novel scheme of Maximum Radio Frequency Energy Harvested Antenna Selection in Two-Way Communication via two multi-antenna Relays in the presence of an interferer under eavesdropper attack. The basic objective of our work is to investigate the Secrecy Performance in Two-Way Multi-antenna Relay network with Interference-aided EH using Maximum Harvested Energy Antenna-Selection Scheme. The impact of some network parameters, namely energy harvesting coefficient, Transmit Power of Sources, Interferer Transmit Power, Global Target Secrecy Rate and no of antennas has been examined on the Secrecy capacity. Simulation results demonstrate that our proposed model improves the secrecy performance significantly as compared to its contrast models. Also a trade-off has been observed between secure transmission and reliable communication. Furthermore, these results serve as a criterion for the deployment of maximum number of antennas for two way communication to enhance the Secrecy Capacity.
