Abstract

The open broadcast nature of the wireless networks makes it vulnerable to the eavesdropper attacks. The physical layer security (PLS) is a grown research field that exploits the characteristics of the physical wireless channel to prevent the eavesdropper interruptions and attacks. The use of the cooperative relay transmission is a method to approach the physical layer security. This paper studies the secrecy performance metrics of the half-duplex two-way multi-relaying technique. A cooperative jamming protocol is proposed to enhance the physical layer security, where the destination sends jamming signals to the eavesdropper node to degrade its channel capacity. However, the relays can act as a jammer and send jamming signals to the eavesdropper node. Moreover, Simulations of the performance metrics namely the secrecy capacity (Cs) and the secrecy outage probability (SOP) applied on the technique are presented and discussed to measure the secrecy level of the proposed technique compared with an existing technique namely half-duplex one-way multi-relaying technique. Based on simulations and discussions the proposed technique outperforms the existing technique in term of secrecy performance.
