Efficient Missing Tag Detection in RFID Systems

Free registration required

Executive Summary

RFID tags have many important applications in automated warehouse management. One example is to monitor a set of tags and detect whether some tags are missing - the objects to which the missing tags are attached are likely to be missing, too, due to theft or administrative error. Prior research on this problem has primarily focused on efficient protocols that reduce the execution time in order to avoid disruption of normal inventory operations. This paper makes several new advances.
