摘　　要：为解决以往基于信任机制的无线传感网络平面式路由协议中存在的问题,如信任计算指标不全面、人工赋权导致权重不可靠、路由节点相关而导致丢包、延迟、能耗等等,提出了一种基于多因子信任机制的无线传感网络安全路由协议SRPMT,该信任机制考虑了节点直接信任、间接信任、剩余能量、节点间距离度量和汇聚节点sink距离等五项信任因子,采用熵权法进行动态赋值权重,采用改进的AODV协议节点不相关多径路由,sink根据信任的链路质量计算出最优路径及备用路径,当多条路径都不可靠之后网络发起路由重建,降低了路由重建频率。仿真结果表明,与TSRP与AODV相比,SRPMT有效降低了网络节点能耗、延迟与丢包率,提高了无线传感网络的安全性。To solve the problems of incomplete trust calculation metrics,unreliability of weights due to manual assignment,packet loss,delay,and energy consumption due to the correlation of routing nodes in previous flat routing protocols of wireless sensor networks based on trust mechanism,a secure routing protocol named SRPMT is proposed for wireless sensor networks based on multi-factor trust mecha-nism.The direct trust value,indirect trust value,residual energy,inter-node distance metric,and the distance from sink metric of nodes with the above five factors are considered.A dynamical weight using entropy measurement is assigned in the proposed new protocol.The uncorrelated node multipath routing establishment using an improved AODV protocol is proposed.The sink node creates both an optimal path and an alternate path which are based on the trust-based link quality.The SRPMT will recreate a new route if neither the optimal path nor the alternate path is reliable.The advantage of using SRPMT is the lower frequency of route discovery.Simulation results show that SRPMT reduces the energy consumption,delay,and packet loss rate of network nodes and improves the security of the network com-pared with both TSRP and AODV.
