This work addresses a moving object equipped with an RFID tag can be tracked by the pre-deployed RFID reader network. However, identifying a large scale of tags that surround RFID readers within the limited time raises a big challenge for RFID-based tracking. To solve this problem, we propose a range-free tracking algorithm. The algorithm works with a basic tracking on a central node which collects tag identi-cation information from all RFID readers. Our system is implemented in the QualNet tool, and the experimental results show the feasibility of RFID- based tracking.
