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. ...doi:10.4108/icst.mobiquitous.2014.258004 dblp:conf/mobiquitous/RuanYSFL14 fatcat:f5yyu7c5frbclcqjzlh2yfnlz4
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  is the similar attempt using RFID signals to passively localize the objects. ...doi:10.1145/2789168.2790100 dblp:conf/mobicom/YangLLLL15 fatcat:ifluhyxgxbgenm2iiy334ctski
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. ...doi:10.3390/s19010068 fatcat:35yxuu2zszgodmevjsuakcv42q
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. ...doi:10.1109/percom.2003.1192765 dblp:conf/percom/NiLLP03 fatcat:lx3jokrvl5axrnnicf6nvibc6e
