Group strategy for remaining tags in anti-collision algorithm for RFID system

In RFID systems, tag anti-collision algorithm is significantly important for fast tag identification, especial in mobile scenarios. In this paper, we propose group strategy for remaining tags algorithm (GSRA for short). The theoretic analysis shows that the system efficiency only concerns rate of migration and static system efficiency, and is not related with the number of tags. The simulation result demonstrates that GSRA algorithm achieve 240% in collision tree algorithm and 20% with respect to the system efficiency.
