Novel Centroid Localization Algorithm for Three-Dimensional Wireless Sensor Networks

In this paper, we propose a new localization algorithm which can be effectively used in three-dimensional (3D) wireless sensor networks. This scheme needs no additional hardware support and can be implemented in a distributed way. The proposed method can improve the location accuracy with relatively low communication traffic and computing complexity. Simulation results show that the performance of the proposed algorithm is superior to that of the conventional centroid algorithm.
