| 摘 要： | 标签碰撞是无线射频识别(RFID)技术中的常见问题,它使得系统效率降低。ALOHA算法是解决此类问题的重要方法,提出了一种基于ALOHA的改进防碰撞算法,并分别给出了应用该方法处理碰撞时,阅读器和标签各自需要执行的程序步骤。仿真结果表明,该算法具有较高的效率,尤其在标签数量较大时相比动态帧时隙算法(DFSA)消耗时隙更少。

| Abstract: | Tag collision is a common problem in radio frequency identification(RFID),it will reduce the efficiency of a RFID system.ALOHA algorithm is an important method to solve this problem.This article proposes a modified anti-collision algorithm based on ALOHA,also gives the pseudo codes of the reader and tag when a collision is detected.Simulation results show that the proposed algorithm is very efficiency and costs fewer slots than DFSA when the number of tags is large. |
