Wireless sensor network boundary node detection is a fundational problem of sensor applications.In order to reduce traffic and improve the accuracy of the boundary node detection,the paper designs an improved boundary node detection algorithm(AIBNDA).The algorithm uses the competition method to select a leading node and the size of the hole to calculate the number of latitude lines.When the number of holes in the network is large,mang rings are constructed to surround the single hole respectively.The paper introduces the ring node dynamic replacement,then the rings are converted into the boundary of the network.The experiments verify the validity of this algorithm in terms of recognition accuracy,reduce traffic and so on.
