Abstract

Node localization is one of the basic problems in wireless sensor networks, the RSSI measurement is widely applied in node localization. The error of RSSI measurement will affect the nodes localization´s precision. The distance geometry constrain has been applied to reduce the error of RSSI measurement, and combined with triangle and centroid location algorithm. Simulation results show that the positioning accuracy has been improved by the localization algorithm compared with triangle and centroid location algorithm based on RSSI measurement.
