Abstract:

In view of the environmental factors that affect the traditional RSSI (Received Signal Strength Indication) ranging precision,a ranging compensation algorithm is proposed to compensate the ranging error caused by environmental factors and to handle multiple RSSI values that the same point receives by the mean value smoothing method to reduce the fluctuation of RSSI values.Simulation and field tests verify that the ranging compensation algorithm improves the ranging accuracy.
