Abstract

The advantages of wireless sensors and RFID technology have been widely acknowledged. Based on the two advanced technologies, we improved our current RFID system by replacing passive tags with active sensor tags. Toward better performance on new system demands, in this paper, we proposes an improved QT protocol called SQT (Sensor tag based Query Tree protocol) which combines the basic principle of QT protocol and a new bit collision detection mechanism for sensor tags identification by a mobile reader. Analysis shows that the SQT protocol reduces identification collisions, which accelerates the identification process. Simulation results substantiate the significant performance improvement by the SQT protocol for sensor tags identification.
