The proliferation of communication and mobile computing devices and local-area wireless networks has cultivated a growing interest in location-aware systems and services. An essential problem in location-aware computing is the determination of physical locations. RFID technologies are gaining much attention as they are attractive solutions to indoor localization applications. In this paper, we propose a new indoor locating system based on the received signal strength intensity. The proposed algorithm introduced a signal strength preprocessing step to improve the accuracy of existing techniques. We investigate optimal parameters in terms of reader and reference tag properties through computer simulations. A new configuration in placing reference tags on the perimeter of a sensing area is also introduced. Comparing with other methods, our experimental results indicate that proposed system achieved more accurate localization with fewer reference tags needed.
