TagTrack: Device-Free Localization and Tracking Using Passive RFID Tags

Wenjie Ruan, Lina Yao, Quan Z. Sheng, Nickolas Falkner, Xue Li
2014 Proceedings of the 11th International Conference on Mobile and Ubiquitous Systems: Computing, Networking and Services  
Device-free passive localization aims to localize or track targets without requiring them to carry any devices or to be actively involved with the localization process.  ...  In this paper, we propose a novel localization and tracking system based on the Received Signal Strength field formed by a set of cost-efficient passive RFID tags.  ...  Device-free RFID-based passive localization in general works as follows.  ...

See Through Walls with COTS RFID System!

Lei Yang, Qiongzheng Lin, Xiangyang Li, Tianci Liu, Yunhao Liu
2015 Proceedings of the 21st Annual International Conference on Mobile Computing and Networking - MobiCom '15  
In this work, we present a system, named Tadar, for tracking moving objects without instrumenting them using COTS RFID readers and tags. It works even through walls and behind closed doors.  ...  Many applications would benefit from such device-free tracking, e.g. elderly people surveillance, intruder detection, gaming, etc.  ...  It obtains a median tracking error of 60cm. TagTrack: TagTrack [19] is the similar attempt using RFID signals to passively localize the objects.  ...

WallSense: Device-Free Indoor Localization Using Wall-Mounted UHF RFID Tags

Liang Ma, Meng Liu, Hongjun Wang, Yang Yang, Na Wang, Yajun Zhang
2018 Sensors  
The system deploys two orthogonal tag arrays in adjoining walls and uses the RSSI and phase information measured by RFID readers to localize the target.  ...  To achieve device-free indoor localization without the active participation of the users, this paper presents WallSense, a device-free indoor localization system based on off-the-shelf Radio RFID (Radio-Frequency  ...  In this paper, we present WallSense, a RFID-based device-free localization system built with Off-the-Shelf RFID readers and tags. 1.  ...

LANDMARC: indoor location sensing using active RFID

L.M. Ni, Yunhao Liu, Yiu Cho Lau, A.P. Patil
Proceedings of the First IEEE International Conference on Pervasive Computing and Communications, 2003. (PerCom 2003).  
Growing convergence among mobile computing devices and embedded technology sparks the development and deployment of "context-aware" applications, where location is the most essential context.  ...  In this paper we present LANDMARC, a location sensing prototype system that uses Radio Frequency Identification (RFID) technology for locating objects inside buildings.  ...  RFID tags are categorized as either passive or active. Passive RFID tags operate without a battery.  ...
