Abstract

Radio Frequency Identification (RFID) is a hot research topic in recent years. And connecting RFID readers to construct a mesh network, which is defined as RFID Reader Network herein, by short-range wireless technologies (such as ZigBee) is a promising architecture. RFID reader can sense (identify) persons, animals, vehicles and goods by interrogating transponders tagged on them. From this perspective, RFID Reader and Reader Network is Sensor and Sensor Network that is context-aware, respectively. However, only sensing is not enough in many scenarios. Therefore, in this paper, we propose a tracking algorithm, coined Virtual Route Tracking (VRT), to realize tracking persons or objects in RFID Reader Network.
