摘要
文中首先介绍了RFID系统中3种不同的碰撞的产生原理,然后研究了最常见的多标签碰撞问题及其对应的防碰撞算法,并重点研究了两种目前工程中较常用的防碰撞算法DFS-ALOHA和Q-ALOHA算法的性能及其应用场景。希望文中介绍对需要解决标签碰撞问题的读者具有一定的启发作用。
This paper introduce the collision cause of radio frequency identifi cation system,then discussed the most common collision form that is multi-tag collision and its anti-collision algorithm.This paper mainly focus on the performance and the application scenarios of dynamic framed slot ALOHA and query ALOHA algorithm whichmostly used in engineering.Therefore I hope that through this paper will enlighten those readers which need to solve multi-tag collision problem.
