摘要: 针对RFID系统的RRE(Redundant Reader Elimination)算法和LEO(Layered Elimination Optimization)算法的不足,提出了一种I-RRE(Improvable-Redundant-Reader Elimination)算法。该算法增加候选holder,优先开启阅读器射频范围内的标签候选holder为0的阅读器,达到冗余阅读器数目最大化、工作阅读器数目最小化的目的。利用随机产生的RFID系统网络来模拟现实RFID系统环境,该环境根据参数不同的阅读器以及标签数量来模拟不同的场景,最后对冗余阅读器改进算法与其他算法对比分析。

Abstract: Some redundant readers are not closed but they are still working in RRE algorithm and LEO algorithm.In order to resolve this problem,an RRE improved algorithm(Improvable-Redundant-Reader Elimination,I-RRE) is proposed.The algorithm adds candidate holder.It makes the reader work whose candidate holder is 0 in the reader RF range,so the number of redundant readers is the maximum and the number of work reader is the minimum.Randomly generated RFID system is used to simulate the actual RFID system environment.In this environment,different scenarios are imitated based on different parameters of reader and the number of labels.I-RRE algorithm is compared with others briefly.
