On the security and reliability performance of SWIPT-enabled full-duplex relaying in the non-orthogonal multiple access networks

The performance of the simultaneous wireless information and power transfer (SWIPT) enabled full-duplex (FD) relaying in non-orthogonal multiple access (NOMA) networks is investigated in both reliability and security aspects. More precisely, for the viewpoint of reliability, we derive in the closed-form expression the outage probability (OP) at both end-users. On the other hand, intercept probability (IP) is considered a helpful metric to measure the security of the considered systems. Moreover, we derive the IP in the closed-form expression too. Numerical results are also given to confirm the correctness of the derived mathematical framework as well as to identify the insights of both metrics as a function of some key parameters such as the transmit power, the power-splitting (PS) ratio, and the power allocation ratio.

Automated summary

This paper investigates the reliability and security aspects of simultaneous wireless information and power transfer (SWIPT) enabled full-duplex (FD) relaying in non-orthogonal multiple access (NOMA) networks. The outage probability (OP) at both end-users is derived in closed-form expression from the reliability viewpoint. Intercept probability (IP) is considered a useful metric to measure system security, and a closed-form expression for IP is also derived. Numerical results confirm the correctness of the mathematical framework and provide insights into the impact of key parameters such as transmit power, power-splitting (PS) ratio, and power allocation ratio on both metrics.
