Joint Relay and Jammer Selection for Secure Two-Way Relay Networks
In the traditional method the joint relay and jammer selection in two –way cooperative networks is investigated. A two way cooperative network comprise of two sources, a number of the intermediate nodes and one eavesdropper with the restraint physical layer security. In the proposed algorithm two or three intermediate nodes are taken for the enhancement of the security against the attacker eavesdropper. The nodes that are used performs the following function: the first node operates in the conventional relay mode, and with the help of the amplify and the forward protocol, it assists in the delivering of the data from one source to the destination. in order to create intentional interference upon the malicious eavesdropper , the second and the third node are used in different communication phases as jammers. In this the jamming and non jamming scheme compared, firstly to find were the intermediates nodes are disturbed randomly and rarely , in this non jamming is better than the jamming scheme and secondly it is find were the intermediate nodes are gathered as close cluster in this jamming scheme is less effective than the non-jamming . so a hybrid a scheme is introduced to switch between the jamming and non jamming modes , the results obtained shows that the hybrid scheme is better and efficient
