摘要
射频识别技术中,防碰撞问题是提高系统读取效率的关键问题。文章在传统防碰撞算法的基础上,提出一种优化的基于动态帧时隙ALOHA的防碰撞(Improved dynamic framed slotted ALOHA,IDFSA)算法。实验结果表明:IDFSA算法大幅度地提高了系统的时隙利用率和读取效率。
In radio frequency identification technology,collision issue is a significant one which limits the reading efficiency of the systems.In this paper,an Improved Dynamic Framed Slotted ALOHA(IDFSA) collision algorithm is put forward,which is based on conventional algorithms.Simulation results indicate that IDFSA highly improves the slot utilization rate and the reading efficiency comparing.
