Wireless sensor networks(WSNs) distributed algorithm is a node fault diagnosis algorithm that can be used for WSNs.The data fusion is used between the nodes and its neighbor nodes to diagnose fault nodes.However,the calculation of distributed algorithm is very complex,it wastes a lot of nodes'energy,and also the distributed algorithm using a unique threshold across the networks will reduce the diagnostic precision.Clustering node fault diagnosis algorithm proposes a LEACH-DFD algorithm,which achieves the nodes'fault diagnosis by the cluster head.This algorithm saves lots of energy,and it uses optimized segmentation threshold to improve the diagnosis precision,so the impact of node failure rate is reduced.
