Three-dimension(3D) weighted centroid algorithm is extended from two-dimension(2D) space.A novel weighted centroid location algorithm based on distance function and index function is proposed respectively
to improve localization precision of the traditional 3D centroid algorithm.Simulation result shows the two new algorithms improve localization precision obviously.The average localization error decrease by 8%
and the network coverage rate reaches above 92 % at 15 % ratio of anchor node.
