摘　　要：为了深入分析无线射频识别系统中的标签碰撞问题以及解决该问题的防碰撞算法,对现有的各种防碰撞算法进行了分类,将其分为基于Aloha的算法、基于树的算法以及混合算法三类。对每种算法的核心思想进行了深入探讨,并对各种算法的特点与不足进行了对比分析。从吞吐率、时延等方面对算法性能进行了评价和比较,并指出了未来的研究方向。To analyze the tag-collision issues and the anti-collision algorithm in Radio Frequency IDentification （RFID） system, the various existing algorithms were classified into three types： Aloha-based, tree-based and hybrid algorithms. The core idea of each algorithm was discussed in depth, and the characteristics as well as the shortcom- ings of various algorithms were compared and analyzed. The performances of these algorithms were evaluated and compared on the throughput, identification delay and other aspects. The future research directions were suggested.
