Abstract: In wireless networks the security is provided by using the physical layer security that has been recognized as a highly capable design paradigm. The friendly jammers are placed in the access points in order to confuse the signals sent by the eaves droppers. In the proposed technique jamming plays a mean role by creating unwanted signals to baffle the probable eavesdroppers and significantly improves eminence and consistency of secure transportation between legitimate nodes. This jamming signal includes imaginary limits for the exploration of secrecy rate. Particularly, the imaginary limits explore the achievable secrecy rates of user cooperation based jamming whilst the centralized and game theoretic based preceding techniques are reviewed for practical implementations. Jammers should have strong self-interference and the signals.
