Study and Optimization of the Anti-collision Mechanism Based on EPC Gen2 Protocol

The problem of the collision when multiple tags access to a reader at the same must be solved in RFID system.This paper introduces the anti—collision algorithm in the EPC Gen2 protocol,and optimize the standard Q value adjustment algorithm and multi—tag reading mechanisms under the conditions that do not change the original order form and not to increase the command,through the analysis of a variety of programs to propose an optimized multi—label response mechanism.
