Target locating is a kernel and challenging function of many applications based on wireless sensor networks. Many existing approaches of target locating employ the binary detection model. In this paper, we first propose a probabilistic-based detection model for wireless sensor networks in a three-dimensional region, which is more realistic in reality. We further design a probability-based target locating algorithm and evaluate this algorithm under four typical deployment schemes of wireless sensor networks. Simulation results show that our simple and effective algorithm can locate the target and save much energy during the tracking process of a moving target.
