On maximising tag reading efficiency of a multi‐packet reception capable radio frequency identification reader

Abstract

Maximising the tag reading rate of a reader is one of the most important design objectives in radio frequency identification (RFID) systems as it is inversely proportional to the time required to completely read all the tags within the reader's radio field. To this end, numerous techniques have been independently suggested so far and they can be broadly categorised into pure advancements in the link-layer tag anti-collision protocols and pure advancements in the physical-layer RF signal reception model. This study shows by rigorous mathematical analysis and Monte-Carlo simulations that how those two independent approaches can be coupled to maximise the tag reading efficiency in an RFID system, considering a slotted Aloha-based dynamic link-layer anti-collision protocol at tags and a multi-packet reception capable RF reception model at the reader.
