Improved anti-collision algorithm in RFID system
RFID系统中一种改进的防冲撞算法

Based on Aloha and binary tree algorithm, this paper proposed an improved anti-collision algorithm in RFID system .When lots of tags need to be identified at the same time, it first estimated the number of unread tags according to the last collision, then divided the tags into different subsets or adjusted the frame size to reduce the collision probability. As a result, the identification efficiency is improved with the proposed method.
