如何将信任管理运用于无线传感器网络(WSN)的路由选择成为近年来研究的一个热点.考虑无线传感器网络的节点安全度、能量约束以及传输可靠度等三个基本因素,完成节点可信度以及最优可信路径(MTP)的度量,引入博弈机制对节点参与路由进行建模,基于可信度设计了一个payoff函数,通过相应的奖惩机制抑制WSN路由中普遍存在的恶意节点、自私节点以及激励措施问题.实验结果表明与WSN中传统的典型路由算法相比,该最优可信路径算法在网络生存时间,路径安全度,传输可靠性等因素方面综合性能显著改善.
How to apply trust management to the routing of wireless sensor network (WSN) has become a hot topic in recent years.With three basic factors of node security, energy constraint and transmission reliability of wireless sensor network, the node reliability and (MTP), a game mechanism is introduced to model the node participation route. A payoff function is designed based on the credibility. Through the corresponding reward and punishment mechanism, it suppresses the malicious nodes, selfish nodes, selfish nodes, Incentive problem.The experimental results show that compared with the traditional typical routing algorithms in WSN, the optimal trusted path algorithm has significantly improved overall performance in terms of network lifetime, path security, and transmission reliability.
