Abstract: In the wireless sensor network, the node localization is one of the core technologies in this domain. To solve the low localization caused by the traditional centroid location algorithm, based on the division of the wireless sensor network, the author put forward a renewed algorithm by combining the RSSI measuring technique with the centroid al- gorithm. The algorithm combines the received RSSI value with the divided area of the network and forms an estimated area of the unknown nodes so as to locate the node. Simulation shows that compared with the traditional centroid loca- lion algorithm,the error location has been significantly improved by this algorithm.
Key words: Centroid algorithm, RSSI, Regional division
