针对无线传感器网络安全路由中恶意节点的转发及合谋攻击等问题,同时兼顾考虑节点之间的链路质量,设计了基于信任的无线传感器网络安全路由算法,对该算法的ETX的计算、节点信任值的计算、组合路由指标的合成以及路由设置等四个模块进行详细设计。最后通过仿真实验,并与CTP及TSR算法进行对比分析,其结果表明RTSR算法能够有效地提高网络的传递率,保证路由的安全性与可靠性,降低总的传输次数,减少网络的能耗。

Aiming at the malicious nodes in wireless sensor network security routing forwarding, and the problem of conspiring to attack both considering the link quality between nodes at the same time, a wireless sensor network security routing algorithm based on trust is designed. For the calculation of the algorithm of ETX, node trust value computation, the synthesis of routing metrics and routing setting lamp four modules are designed in detail. Finally through the simulation experiments, and compared with algorithm based on the CTP and TSR analysis, the result shows that RTSR algorithm can effectively improve the network transmission rate, guarantee the routing security and reliability, reduce the total number of transmission, reduce the energy consumption of the network.
