Expanding Horizon and Capture Effect in RFID Systems

Tags: rfid

Overview RFID has been the subject of much research recently, which yielded very efficient singulation algorithms, such as Tree Walking Algorithms, or framed slotted Aloha. However, there is still room for improvement in the case of multiple readers, and also in the power efficiency of singulation algorithms. This paper addresses two schemes that might improve energy consumption and singulation time in RFID systems. First, the paper considers expanding horizon, a form of power control at the reader introduced, and see how it impacts the energy consumption and singulation time in the case of a single reader.
