摘要： 提出一种基于平均海明距离的无线传感器网络安全路由算法。该算法利用节点的实时包传递率短序列和正常运行短序列之间的平均海明距离，检测节点是否正常。在节点中引入邻近节点表，对恶意节点进行隔离，在重新组簇的过程中节省节点能量，在路由选择时综合考虑能量、跳数和路径可靠性等因素。仿真实验结果表明，该算法能耗较低，具有较高的检测率。

Abstract: This paper proposes a secure routing algorithm for Wireless Sensor Network(WSN) based on average Hamming distance. It judges the nodes is whether normal according to the average Hamming distance between real and normal packet ration short sequence of the nodes, and it introduces a kind of neighborhood table, which saves the energy of node in the process of reclustering when malicious node emerges. It considers the energy, hop counts and route relibility comprehensively during the routing selecting. Simulation experimental results show the algorithm has a low power consumption and high detection accuracy.
