Improvement to the anticollision protocol specification for 900MHz Class 0 radio frequency identification tag

摘要

This paper proposes a modification to the existing anticollision protocol put forth in version 1.0 protocol specification for 900MHz Class 0 RFID Tag. The version 1.0 specification uses a binary tree approach to singulate one RF tag ID at a time. The proposed change reduces the overall read time of a given number of RFID tags by resetting to the appropriate node, for every consecutive read cycle. The present standard resets to the root node of the binary tree for every read cycle.
