PERFORMANCE EVALUATION OF SECURITY WHEN USING ARTIFICIAL NOISE FOR ONE-WAY FULL-DUPLEX RELAY NETWORKS

Abstract

In this paper, we are presenting a method to improve physical layer security (PLS) in wireless communication networks. Specifically, we would like to propose a one-way full-duplex (OWFD) relay network model with artificial noise (AN). The model consists of five nodes (source node, destination node, relay node, eavesdropping node, jamming node). To evaluate the security performance of the model, we analyzed key performance metrics such as the secrecy outage probability (SOP) and the system's secrecy throughput (STP) through deriving closed-form expressions for SOP and STP. Simulation results verify the proposed expressions using the Monte-Carlo method. The findings of this study demonstrated a significant improvement in security performance compared to previous researches. Additionally, the proposed model has highlighted the feasibility of implementing PLS techniques in OWFD relay networks.
