A Middleware-Based Algorithm for Redundant Reader Elimination in RFID Systems
Shun‐Zheng Yu · Dianzi xuebao · 2012
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.
