SPRINGERBRIEFS IN ELECTRICAL AND COMPUTER ENGIN...

This SpringerBrief examines the use of cheap commercial passive RFID tags to achieve accurate
device-free object-tracking. It presents a sensitive detector  named Twins  which uses a pair
of adjacent passive tags to detect uncooperative targets (such as intruders). Twins leverages a
newly observed phenomenon called critical state that is caused by interference among passive
tags. The author expands on the previous object tracking methods  which are mostly device-based
and reveals a new interference model and their extensive experiments for validation. A
prototype implementation of the Twins-based intrusion detection scheme with commercial
off-the-shelf reader and tags is also covered in this SpringerBrief. Device-Free Object
Tracking Using Passive Tags is designed for researchers and professionals interested in smart
sensing  localization  RFID and Internet of Things applications. The content is also useful for
advanced-level students studying electrical engineering and computer science.
