The Analysis and Research of the Hybir Redundancy Elimination Algorithm (HRRE) Based on RFID Middleware Reader

摘要

LEO (Layered Elimination Optimization) algorithm and RRE (Redundant Reader Elimination) algorithm are widely used because of their needless of complicated operations and efficient redundant elimination ability. This study puts forward an improved hybrid redundant elimination algorithm HRRE. By introducing the candidate holder, the maximize redundant-readers and the minimize work readers are guaranteed. At the same time the use of label information in the RFID middleware to identify the reader redundant state reduces the performance effect of the system effectively which is caused by write operation. The power consumption of the system caused by the reader write information to label is also reduced at the same time. The simulation results show that the improved hybrid redundancy elimination algorithm has a good solving effect.
