基于演化博弈的Ad hoc网络合作机制

Cooperation mechanism in Ad hoc network based on evolutionary game

设计一种不需要涉及外界手段(信誉或虚拟货币)的合作机制,并应用生态仿真方法,对Ad hoc网络节点的报文转发过程进行博弈仿真.结果表明,无论在有或无噪声条件下,合作机制GTFT策略均能在种群中促进合作的涌现并保持演化稳定,而Gradual策略加噪之后表现并不稳定并且会加重网络负载,增加网络时延.

The paper proposes a dynamic game-theoretic model to facilitate the study of the non-cooperative behaviors, and designs an incentive schemes without an external mechanism （reputation or virtual currency） based on analyzing the cooperation of evolu- tion concerning on packets forwarding. Simulation results show that GTFT strategy can inforce the emergence of cooperation and keep evolution stablely in noise/noiseless environment.
