LV Shi-lei, YU Shun-zheng. A Middleware-Based Algorithm for Redundant Reader Elimination in RFID Systems[J]. Acta Electronica Sinica, 2012, 40(5): 965-970.
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.
