For when the wireless sensor network sensor node random distribution is stronger

the node energy can get effective supplement

once the node energy run out

can cause node failure.Traditional test methods cannot because cant be accurately extract node failure features

cause failure detection of node accuracy is not high.In order to solve the problems

the article proposes a kind of based on fuzzy clustering failure node of the search algorithm

through calculation wireless sensor node energy consumption characteristics of fuzzy clustering probability

applying fuzzy probability judge failure node position.The experimental results prove that the method can effectively of wireless sensor network failure to detect nodes

good results.
