基于位编码单元的双时隙防碰撞算法
A Bi-slot Anti-collision Algorithm Based on Bits Coding Unit
摘要
Abstract
In RFID system,tags collisions occur while a reader attempts to identify multiple tags at the same time. Propose a bi-slot RFID anti-collision algorithm based on bits coding unit by setting a Bits Coding Unit ( BCU) in every tags. In this algorithm,the bit encoding unit is used to recode the collision bit information,so that the reader which does not need to traverse queries can identify the collision bit information of tags once,thereby reducing the number of queries and the identification delay,making the tags can be identified quickly. Analysis of performance and the results of simulation show that the proposed algorithm improves the identification efficiency under the condition of a lot of tags.关键词
