The Cooperation Of Nodes In Ad Hoc Network Based On Nash Equilibrium

Ad hoc network is the hotspot of network research. Especially recently more and more researchers presented their solutions in all aspects of ad hoc network. Among which the cooperation of nodes is the point. In which way that the nodes can overcome their restriction to relay other nodes'data packages. Some researchers have given a few mechanisms such as incentive mechanisms, virtual currency and so on. In this paper, the author presents a new one, which based on the game theory of economics. All the nodes taking part in the packages relaying reach a status of game equilibrium, accurately, the Nash equilibrium. The nodes in equilibrium don't depend on the incentive methods come from outside, and their actions will have infection on themselves in the end.The author refers some idea, and introduces the Nash equilibrium into the nodes cooperation. The author gets his expected result by simulating the network in NS-2. From the result, the author's idea gets affirmation.
