中文摘要：
冗余阅读器判别是大规模RFID系统性能优化的重要问题之一．本文基于EPE网络架构提出一种阅读器去冗余算法MRRE．该算法利用RFID中间件的标签信息判别冗余阅读器，不需阅读器对标签写入信息．仿真结果表明，MRRE算法比LEO＋RRE算法在冗余阅读器检测率上提高了6．27％-20．80％，在系统处理的标签信息量上降低了4．50％．35．73％，而且在系统部署合理性方面更具优势．
英文摘要：
The elimination of redundant readers is a significant approach to optimize the performance of large-scale RFID systems. In this paper, an algorithm for redundant reader elimination （MRRE） is presented, which is based on the architecture of EPC network. The MRRE eliminates redundant readers using the tag information in the RFID middleware, without the ＂write-to-tag＂ operations. Simulation results reveal that, compared with the lEO ＋ RRE, the MRRE can improve the detection rate of redundant readers by 6.27% - 20.80% while the processed quantity of labels in RFID systems can be decreased by 4.50% - 35.73%. Moreover, it can enhance the deployment rationality of RFID systems.
