摘　　要：针对无线传感器网络经典的分簇路由协议LEACH中存在的安全性低、网络生存时间短的问题,提出一种基于模糊控制和节点可信的安全分簇路由协议,首先设计一种模糊控制系统,以节点的直接信任值和间接信任值作为模糊控制系统的输入、输出节点的综合信任值;再将获得的综合信任值和节点中心度、节点剩余能量作为第二层模糊控制系统的输入,输出为“成为簇头的机会”值输出;其次通过计算确定最优簇数k值,降低迭代过程中的能量消耗。仿真结果表明,该算法能够保证节点的可靠性,合理分配节点能量,延长网络生存时间。Aiming at the problems of low security and short network lifetime in the classic clustering routing protocol LEACH of wireless sensor networks,a secure clustering routing protocol based on fuzzy control and node trust is proposed.First,a fuzzy control system is designed,in which the direct trust value and indirect trust value of the node are used as the input of the fuzzy control system,and the comprehensive trust value of the node is output,Then the obtained comprehensive trust value,node centrality and node residual energy are used as the input of the second layer fuzzy control system to output the value of“the opportunity to become a cluster head”.Secondly,the optimal cluster number k value is determined through calculation to reduce the energy consumption in the iteration process.The simulation results show that the algorithm can ensure the reliability of nodes,reasonably allocate node energy,and extend the network lifetime.
