description The broadcast characteristic of a wireless networks which is exploited in cooperative communications leads to a variety of security vulnerabilities. The increasing number of applications using wireless network such as Internet of Things' applications will make it even more difficult for the existing security system to survive due to many factors such as the open nature of the wireless network, high computational complexity in the current security algorithms as well as the problems related to the key distribution and management. Physical layer security considered an additional security layer to the existing cryptography techniques and for some applications can be stand-alone security. The existing physical layer security techniques are classified into five main categories: code, power, theoretical, signal and signal detection approaches. 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. In this research, 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.
