The invention provides a reliable routing method for wireless sensor network node failure, which is used for evaluating the stability of a link between adjacent nodes in a wireless sensor network based on a link maintenance time measurement standard of link quality. The problem that a traditional routing protocol is difficult to accurately evaluate the link stability in a high-dynamic and high-density network is solved, and a quantitative index is provided for the stability of network topology; the invention discloses a reliable routing method for wireless sensor network node failure. The method comprises the following steps: step 1, a routing discovery stage: initializing a network, discovering neighbors and establishing a network topology; step 2, a route selection stage; and performing a dynamic search routing algorithm based on the link stability, and outputting an optimal route. 本发明提供一种面向无线传感网节点失效下的可靠路由方法，该方法基于链路质量的链路维持时间衡量标准，用于评估无线传感器网络中相邻节点之间链路的稳定性，解决了传统路由协议在高动态性和高密度网络中难以准确评估链路稳定性的问题，为网络拓扑的稳定性提供了量化指标；一
