Study of Wireless Sensor Network Localization Algorithm Based on RSSI
基于RSSI测距的传感器网络定位算法研究

Path loss for radio-wave propagation is transformed into distance according to theoretic or empirical model based on range measurement of RSSI(Received Signal Strength Indicator).In the actual application environment,because of multi-path,diffraction,obstacles and other factors,path loss error resulted in the positioning error.The new location algorithm ERSS based on RSSI was proposed by analysing error region produced during two-dimension space localization.Simulation results show that the ERSS algorithm h...
