Abstract
This paper presents the indoor object management system implemented in sensor-embedded environment using active Radio Frequency Identification (RFID) technology. The proposed system provides users with functions to management targeted objects in the room, monitor their locations in realtime, view and search for the movement history of objects from log database. The proposed object localization method is based on the analysis of RF signal strength retrieved from RFID system and position tracking of user in the room using floor-distributed pressure sensors. The experiment results have shown that the integration of sensors can significantly reduce the effects from external interferences that affect the performance of RF signal strength analysis, and result in the improvement of indoor object localization accuracy.
