Fast Identification of the Missing Tags in a Large RFID System

RFID (Radio-Frequency IDentification) is an emerging technology with extensive applications such as transportation and logistics, object tracking, and inventory management. How to quickly identify the missing RFID tags and thus their associated objects is a practically important problem in many large-scale RFID systems. This paper presents three novel methods to quickly identify the missing tags in a large-scale RFID system of thousands of tags. The authors' protocols can reduce the time for identifying all the missing tags by up to 75% in comparison to the state of art.
