The existing location method usually needs to establish network and the energy consumption is inequality. So it does not apply to a small number of mobile nodes in wireless sensor networks. Aim at the positioning of each node in wireless sensor network, clustered location algorithm is proposed on the premise of analyzing the computational complexity and the energy consumption of positioning. Using Receiving Signal Strength Indication (RSSI) combined with Centroid Localization Algorithm (CLA) to locate the mobile nodes in the cluster. The analysis and simulation results show that the improvement of clustering method can improve the positioning accuracy and reduce the network energy consumption effectively. Then the network life cycle can achieve the longest.
