In opportunistic network as one type of challenged networks where networks contact are intermittent or where link performance is highly variable or extreme. This technique to alter user to speak end-toend methods are unstable. when node are selfish, they may not have incentives to participate in probabilistic routing and also the system performance are degrade, enable to participate that selfish node, This approach will considerably decrease the quantity of retransmissions therefore on scale back the routing overhead and improve the routing performance. so finding the neighborhood node, we tend to use channel awareness mechanism for knowledge transmission and to enhance the standard.
