Abstract:
In order to improve electronic tag identification efficiency,this paper proposes a new anti-collision algorithm to solve ALOHA algorithm ’ s low efficiency and poor reliability and binary tree search algorithm ’ s bad performance when handling large numbers of tags.This new algorithm estimates the number of tags in the effective range at first,then tags are grouped and arranged according to the number,and finally the left tags are recognized by dynamic binary tree search algorithm.The improved radio frequency identification(RFID) tag anti-collision algorithm can keep the throughput rate over 36.8% based on high reliability,and overcomes the disadvantage of binary tree search algorithm while tags ’number rises.
