摘要：
This paper investigates a cooperative network scenario involving a source, multiple users, and relays, all situated in the presence of multiple eavesdroppers attempting to intercept the secret message transmitted by the source node. To deal with this problem a novel secrecy maximization oriented relay selection (SMORS) scheme is proposed to enhance the physical layer security (PLS) of wireless systems. In this paper, the closed-form expression of intercept probability (IP) for projected SMORS and conventional max–min relay selection schemes over relay fading channels has been derived. It is observed that with an increasing the number of relays and users, the IP decreases significantly for SMORS scheme. Numerical results demonstrate that the presented SMORS scheme superior than the traditional max–min relay selection scheme. © The Author(s), under exclusive licence to Bharati Vidyapeeth's Institute of Computer Applications and Management 2024.
