• DISTANCE MEASUREMENT MODEL BASED ON RSSI LOCALIZATION TECHINQUE IN WIRELESS SENSOR NETWORKS

Abstract

Node localization is one of the basic problems in wireless sensor networks.The localization method based on RSSI measurement is studied in this paper. Because the RF signals are affected by the environment, the exact distance between the nodes cannot obtain by RSSI measurement.The parameters of measurement model are determined by anchor nodes, and further correct the measurement data, which can reduce the measurement. The improved RSSI measurement can improve the accuracy of the unknown nodes localization.
