Design and simulation of the cooperation incentive mechanism in ad hoc network based on evolutionary game

To solve the difficult problem that selfish nodes often initiate attack of lost package and occupy the resources of the other nodes in Ad Hoc networks, we propose a dynamic game model to facilitate the study of the non-cooperative behaviors and design an incentive mechanism which need not involve any logical object, such as reputation or virtual currency in this paper. The simulation results show that GTFT strategy cooperation mechanism can promote the emergence of cooperation in the population and keep evolution stabilization in noise/noiseless environment, but Gradual strategy is not stable and will increase the network load, increasing the network time delay after adding noise. © 2015, ICIC International.
