Abstract

Due to low costs and high applicability in object tracking and building smart environments, passive RFID technologies became very popular in every-day usage. However, there are some MAC level constraints on the efficiency of Reader-Tag communication, because lack of tag computational abilities. In the accordance with standard Framed Slotted ALOHA (FSA) protocols we provide improvement for tag identification which increases throughput of the RFID system and thus minimizes response time from RFID tags. For comparison, simulation results show that our method provide better efficiency then Q-selection algorithm from UHF-Class1-Gen2 standard.
