摘要
对射频识别(RFID)系统中一类解决多标签间碰撞问题的防碰撞算法现状进行了综述,分析了各算法的优势与不足。针对目前最常用的动态帧时隙算法,在分析其帧长调整方法缺点的基础上,提出了一种帧长及分组数动态调整方案。仿真结果显示,改进方案提高了系统的识别效率和稳定性。
Comprehensive review of the research of one kind of anti-collision algorithms and analysis of their disadvantages were provided. Based on the analysis of the frame size adjusting method of the most in common use branch dynamic framed slotted Aloha algorithm, this paper brought forward an improved resolution by dynamically adjusting the frame size and group division, which can consumedly enhance the system efficiency and its stability.
