Abstract:
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 can't 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.
