Anti-Collision Algorithm for RFID Based on Dynamic Packet Query Tree
Based on the analysis of typical binary and dynamic binary search anti-collision algorithm in RFID system, this article proposes a fast and efficient anti-collision algorithm, that is, conduct dynamic packet on tags and adjust query instruction. The performance analysis and experiments show: this algorithm greatly reduces the tag identification time, and increases the identification efficiency of RFID system. At the same time, it reduces information exposure of tags when reader communicates with tags, and effectively decreases the collision probability of tags.
