A Improved EPC Class 1 Gen 2 Protocol with FCFS Feature in the Mobile RFID Systems
Keywords:RFID, tag anti-collision, mobile RFID systems, EPC C1G2
In all anti-collision protocols of RFID standards, EPCGlobal Class 1Â Generation 2 (C1G2) protocol has been most widely used in RFID systems since itÂ is simply, efficient and safety. Similar to most existing anti-collision protocols, TheÂ C1G2 protocol initially aims at tag identification of static scenarios, where all tagsÂ keep still during the tag identification process. However, in many real scenarios, tagsÂ generally move along a fixed path in the reader coverage area, which implies thatÂ tags stay the coverage area only for a limited time (sojourn time). The scenarios areÂ usually called mobile RFID systems. Because the multiple tag identification basedÂ on a shared wireless channel is random, tags entering the reader coverage area earlierÂ may be identified later (random later identification phenomenon). The phenomenonÂ and the limited sojourn time may let some tags lost. In this paper, we propose anÂ improved C1G2 protocol with first come first served feature in mobile RFID systems.Â The protocol can overcome the RLI phenomenon effectively and retains good initialÂ qualities of C1G2 protocol by modifying it slightly. Simulation results show thatÂ the proposed protocol can significantly reduce the numbers of lost tags in mobileÂ RFID systems. The idea of the paper is beneficial for redesigning other existing tagÂ anti-collision protocols so as to make these protocols adapt to mobile RFID systems.
