Abstract - This paper describes an indoor wireless localization method of an RFID reader using passive tags placed at known locations. The reader location is estimated using the received signal strength indication (RSSI) and trilateration. However, in an indoor wireless environment, the RSSI undergoes fading due the presence of unavoidable scatterers. Hence, trilateration under such fading environments would cause errors in localization. In this paper, we examine techniques to reduce the error of the estimated reader positions.
