Abstract: A weighted centroid localization algorithm based on communication hops for wireless sensor network is presented,the hops between the beacon nodes and an unknown node are employed to be the weighted factors of the beacon nodes for improving the localization accuracy.Simulations on the common centroid algorithm and the improved centroid algorithm have also been performed,results demonstrate the later has the better localization effects in general.
