Self-Energy Recycling in DF Full-Duplex Relay Network: Security-Reliability Analysis

Abstract

This paper studied the physical layer se- curity (PLS) reliability of concurrent wireless com- munications. A decode and forward (DF) full-duplex (FD) network with the impact of an eavesdropper was proposed to evaluate the security and reliability. Es- sentially, the DF-FD relay adopted the power-splitting (PS) protocol to gather energy from the source and si- multaneously utilized the self-energy recycling (S-ER) technique by manipulating the loopback interference to increase the harvested energy. By constructing closed- form expressions for outage probability (OP) and in- tercept probability (IP), we offer the trade-off analysis between them. Monte Carlo simulation was conducted to verify the analytical formulations. Furthermore, the key parameters were also examined to play an impor- tant role in selecting the suitable trade-off for the pro- posed system.
