Abstract
In this paper we present an algorithm of mobile node localization based on weighted Cen-troid for wireless sensor networks. The proposed method splits the original sampling period of the Cen-troid algorithm into temporal windows in order to maintain a record of past information during move ment. The selection of the anchor nodes is based on the weights of the temporal window. The RSSI rati os received from the anchor nodes are used as weights to determine the position of an unknown node. The results from simulation show that the proposed algorithm has low computing complexity, low cost and higher accuracy characteristics.关键词
