RFID系统防碰撞协议的研究

碰撞问题是影响RFID系统读取效率的关键问题。分析了RFID系统中二进制树和查询树的防碰撞原理,并针对这些协议在对碰撞连续的标签进行识别时操作效率较低的问题,提出了一种新的协议。该协议是在二者的基础上进行改进的,对三种防碰撞协议的性能进行了比较,新协议能更好地解决射频识别系统中多个标签识别的问题。

Research on anti-collision protocols in RFID system

Collision issue is a significant one which limits the reading efficiency of RFID systems.This paper analyzes binary-tree protocol and query -tree protocol in RFID system.But these protocols are too inefficient to identify tags of continuous collision. This paper gives a new protocol which is an improvement on two protocols.By comparing the performance among three anti-collision protocols,the efficiency of multiple tags identification is improved by the new anti-collision protocol.
