A NEW THREE-DIMENSIONAL LOCALIZATION METHOD FOR WSN
Localization is one of the fundamental problems in Wireless Sensor Networks(WSN).Received Signal Strength Indicator (RSSI)-based localization is widely applied to node Localization.A RSSI-based localization scheme is put forward,which adopts the mean of RSSI data to select anchor nodes with better RSSI values,so as to reduce the interference and deviation.A three-dimensional trilateration method is proposed,employing three selected anchor nodes and a mobile anchor node to locate,and improving location accuracy.Simulation results show that the deviation has reduced significantly compared to traditional trilateration.
