摘要
节点能耗和路径可靠性是移动自组织网络路由需要考虑的关键因素。为了提高能量利用率以及实现网络收益的最大化,在节点理性、自私的前提下,运用博弈论方法建立了转发节点选择的重复博弈模型,设计了节点信任度评价函数,并采用惩戒机制来威慑自私节点,迫使其自愿采取协同合作的策略。仿真结果表明,提出的路由算法能够均衡网络的能量消耗,提高分组投递率,延长网络的生存时间。
Energy consumption and path reliability are the key issues in mobile Ad hoc networks. In order to improve energy efficiency and maximize networks payoff,a repeated-game theoretic model is proposed for selecting forwarding nodes under the conditions of selfish and rational nodes,a trust evaluation function is designed,and punishment mechanism is used to deter the selfish nodes and force them to take cooperation strategy. Simulation indicates that the proposed routing algorithm can keep the balance of energy consumption and improve the packet delivery ratio and prolong network lifetime.
