Cooperative Jamming for Secrecy of Wireless Communications

This paper explores cooperative jamming for security in wireless networks. No location data of eavesdropper is available, meanwhile no constraint on the figures of eavesdroppers is posited. A cooperative jamming approach is introduced for jamming the eavesdroppers any location in the system, even through the eavesdroppers are established quite adjacent to the sender or the receiver. The main ideas behind the strategy are to jam eavesdroppers by a divide and conquer strategy, and apply the advantageous jamming signal which is generated from the sender or the receiver to solve the problem of adjacent eavesdropper. evaluation and simulation consequences expose that cooperative jamming has the ability to improve the secure performance, and it can be employed to establish initial connections in wireless networks.
