The open nature of the wireless networks makes them vulnerable to the eavesdropper attacks. Cooperative relay transmission is a popular method to prevent the attacks of the illegal nodes. This research proposes a cooperative jamming protocol to enhance the physical layer in wireless cooperative networks, where the destination sends a jamming signal to the eavesdropper node to degrade its channel capacity. Simulations of the secrecy performance metrics in terms of the secrecy capacity and secrecy outage probability are presented and discussed to measure the security level of the proposed jamming protocol. In this paper, different channels namely Rician fading, Rayleigh fading, and Additive White Gaussian Noise (AWGN) channels are investigated in the half-duplex two-way relaying system to obtain the maximum secrecy performance. Based on the results, the highest secrecy capacity is achieved by using the Rician fading channel for transmission from the source to the destination and using the Rayleigh channel as the jamming link to degrade the eavesdropper capacity.
