Abstract:

RFID system is a wireless technology that can transfer data between tags andreaders via radio frequency. In an RFID network, readers are located close to eachother to obtain optimal connectivity and sufficient coverage. In such anenvironment, which is called dense reader environment (DRE).Different types ofcollisions such as Reader-to-Reader and Reader-to-Tag ones, often lead to seriousproblems such as decreasing the performance. Accordingly, providing anappropriate method to resolve reader collision appeared to be one of the mostimportant research topics in the field. To solve this problem, different methods havebeen introduced of which NFRA protocol has higher throughput. In this paper, weuse multi-channel technique and sift distribution function on the NFRA protocol toimprove RFID system throughput while avoiding increase in reader collision. Inaddition of supporting mobile reader, the proposed method provides higherthroughput compared to other protocols in dense environments
