One important application of sensor network is in target locating and tracking.The use of binary sensor is a good choice for decreasing transmission consumption.Based on the recursive centroid algorithm and dynamic clustering structure, a distributed recursive centroid algorithm was proposed and used in distributed target tracking in binary sensor network.Simulations results show that the new algorithm can track target effectively, decrease energy consumption and computing complexity in the case of high density nodes, large detection range and short sampling period, thus can prolong the lifetime of the network.
