Abstract :
RFID technology is gaining much attention for indoor localization because of its advantages such as non-contact and non-line-of-sight nature. In this paper, we study two typical approaches using active RFID for indoor location sensing: LANDMARC and VIRE, and point out that the latter approach with a fixed threshold of received signal strength indication (RSSI) difference which determines the elimination of unlikely positions does not work well in complicated indoor environments with severe radio signal multi-path. Analysis of two important factors in VIRE directs us some improvements for adaptation to enhance the accuracy of indoor localization.
