Abstract EN
Cooperative relaying communication is one of the green communication technologies since it shortens the communication distance and saves the transmit power.
In this paper, the physical-layer security (PLS) of a multisource multirelay cooperative relaying communication network is investigated by considering the influence of cochannel interference from a security-reliability tradeoff (SRT) perspective.
First, the SRT performance is characterized by the outage probability (OP) and the intercept probability (IP).
In particular, the IP encountered at the eavesdropper is used to evaluate the security performance, while the reliability performance is analyzed in terms of the OP experienced at the destination.
Then, under the impact of multiple cochannel interferers, the intercept probabilities and the outage probabilities of both the conventional direct transmission (DT) strategy and relay selection (RS) strategy are derived in closed-form expressions over Rayleigh fading channels, respectively.
Simulation results are provided to validate the theoretical analysis.
It is shown that when the OP (reliability) requirement is relaxed, the IP (security) performance improves and vice versa.
It confirms that there is an SRT existing between the OP and the IP.
Meanwhile, a better SRT performance can be achieved by increasing the number of sources, relays, and cochannel interferers.
In addition, it is also shown that the RS strategy generally outperforms the conventional DT strategy in terms of the product of the IP and the OP.
