| 摘 要： | 时隙ALOHA是无线射频识别系统中常用的抗碰撞算法，采用时分复用的方式，标签在指定的时隙内与阅读器进行数据交换。该文采用动态帧时隙分配法，使标签分配到的时隙碰撞概率降低，时隙数量根据系统碰撞数量进行实时有效调整，仿真结果表明，系统识别效率得到明显提高。

| Abstract: | Slotted ALOHA is commonly used protocol in anti-collision of RFID system.It uses TDMA mode to exchange their data.Tags can only translate its information in a slot.This paper introduces a dynamic frame distributed slots algorithm, which can reduce the rate of collision tags, and the slots can be changed according to the quantity of collision immediate.Simulation results show that the rate of identifying is improved in evidence. |
