An Improvement Approach of Indoor Location Sensing Using Active RFID

The proliferation of mobile computing devices and wireless networks has fostered a growing interest in location sensing systems and services. In this paper we present an improvement approach of indoor location sensing using active RFID system. This is a location sensing system that uses radio frequency identification (RFID) technology for locating objects inside a building. The major advantage of this system is that it improves the overall precision of locating objects by utilizing array of reference tags and some mathematic algorithms. Based on our analysis, we demonstrate that the ability of using active RFID to estimate user location with a high degree of accuracy. Although RFID is not designed for indoor location sensing, this algorithm can be used for indoor location sensing, and added to make RFID technologies competitive in this new and growing market
