Efficient Tag Identification in Mobile RFID Systems

In this paper, the authors consider how to efficiently identify tags on the moving conveyor. Considering conditions like the path loss and multi-path effect in realistic settings, they first propose a probabilistic model for RFID tag identification. Based on this model, they propose efficient solutions to identify moving RFID tags, according to the fixed-path mobility on the conveyor. A dynamic program based solution and an adaptive solution are proposed to select optimized frame sizes during the query cycles. Simulation results indicate that by leveraging the probabilistic model their solutions can achieve much better performance than using parameters for the ideal propagation situations.
