An improved RSSI-based centroid localization algorithm in wireless sensor networks

RSSI-based localization is one of the hot spots in wireless sensor networks nowadays. For improving the locating accuracy, an improved RSSI-based centroid localization algorithm by using a new method to reduce the error of RSSI measurement is presented in this paper. The simulation experiment results prove that this algorithm can obviously improve the locating accuracy compared to other RSSI-based triangle and centroid localization algorithms.
