Analyzing Selfish Behavior in Opportunistic Networks

Some nodes may perform in selfish way in opportunistic networking activities to save their own resources. Once selfish nodes become more, how they will affect the whole networking system is an interesting research question. In this paper, we analyze the selfish behaviors for several popular routing protocols in opportunistic network. Also we made some simulations to check the influence of varying the degree of cooperation. Besides, we also study some strategies in MobiCent in preventing selfish behavior. The experiment result shows encouraging signal that MobiCent and other strategies are useful to prevent selfish behaviors.
