Research of Avoid the Selfish Behavior in Mobile Ad Hoc Networks Based on Repeated Game

In a mobile ad hoc network (MANET), each node communicated with other nodes has relied on the intermediate nodes. But selfish nodes which aimed to get the greatest benefits from the MANET, like battery life and bandwidth. In this paper, we defined a half selfish node which is not selfish always but sometimes. Then we used the repeated game in MANET to avoid the half selfish nodes. Lastly, we have a simulation with NS-2 to test our scheme weather successful or not. Through the simulation, we proved our scheme is successful.
