摘　　要：A Wireless Sensor Network(WSNs) fault-tolerant protocol is proposed in this paper.By setting up a robust cluster topology,the fault-tolerant algorithm can search any faulty node in the path and revise the path furthermore.Once the cluster head fails,it will be substituted by other alternative cluster heads with the lowest cost,and the path will be re-established.Experiments show that this algorithm can not only locate the faulty nodes in the path accurately,shield the influence of the error node in clusters,but also reduce the retransmission times of relevant data caused by error node.Therefore,the proposed algorithm is effective and sufficient enough to resist malicious attack and node losses.In energy consumption aspect,compared with others,the proposed algorithm has a more advantage in energy conservation.A Wireless Sensor Network （WSNs） fault-tolerant protocol is proposed in this paper. By setting up a robust cluster topology, the fault-tolerant algorithm can search any faulty node in the path and revise the path furthermore. Once the cluster head fails, it will be substituted by other alternative cluster heads with the lowest cost, and the path will be re-established. Experiments show that this algorithm can not only locate the faulty nodes in the path accurately, shield the influence of the error node in clusters, but also reduce the retransmission times of relevant data caused by error node. Therefore, the proposed algorithm is effective and sufficient enough to resist malicious attack and node losses. In energy consumption aspect, compared with others, the proposed algorithm has a more advantage in energy conservation.
