Divide and Conquer: Detecting and Tracking Passive RFID Tags in Retail Spaces

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Detecting and tracking items marked with passive RFID tags are essential in modern retail stores, in which the RFID tags are used for inventory control and checkout-free shopping. In many retail stores, passive RFID tags replace traditional bar codes for payment processing and inventory control. Since the typical operational distance of RFID readers for most practical cases is very short (about several feet), to cover the entire store, there is a need for several RFID readers for large retail stores. The issue addressed in this paper is the optimal placement of RFID readers, which provides full coverage of a given entire space, subject to cost, delay, and load balance constraints, using a minimal number of RFID readers. Using the "divide and conquer"strategy, several coverage schemes are introduced and analyzed.
