Energy-efficient cluster based wireless sensor networks are often used to transmit information.In case of failure in WSN,the diagnosis accuracy of the cluster-head nodes should be guaranteed.In this paper,a fault self-diagnosis algorithm is presented with two steps to determine the final state of each node:first,the sensor nodes are identified based on comparisons of data from neighboring nodes,and then further tests are performed to avoid diagnosis errors.Simulation results show that the two-step algorithm has good accuracy and precision of diagnosis.
