摘要

在RFID系统中,标签之间的碰撞问题一直是人们关注的焦点。本文提出了哈希树抗碰撞算法,该算法采用哈希运算为标签分配插槽,并使用树搜索方法在冲突插槽队列中识别冲突标签。该算法不需要读取器测试碰撞位的精确位置,其性能优于基于ALOHA的算法36.8%以上。

Design of Hash-Tree Anti-collision Algorithm
In RFID system, the problem of the collision between tags is a focus topic. The Hash-tree anti-collision algorithm was proposed in the paper, which adopted hash operation to allocate slots for tags and used tree searching method to identify collision tags in the queue of collision slots. The proposed algorithm doesn't require readers to test the precise location of collision bits, and its performance beyond 36.8% is better than ALOHA- based algorithms.
