DEVICE-FREE ELECTROMAGNETIC PASSIVE LOCALIZATION WITH FREQUENCY DIVERSITY

Device-Free Passive Localization

This report describes a Device-Free Passive Localization System (DfP). The system provides a software solution over nominal WiFi equipment to detect the presence and track intruders in an area of interest. The system is based on measuring the changes in the received RSSI at a fixed receiver form a fixed transmitter. Using RSSI values for multiple transmitters and monitoring points, we show a sy...

Device-Free Electromagnetic Passive Localization Using Link Line Information in Wireless Sensor Networks

The electromagnetic passive localization without the need of carrying any device, named device-free passive localization (DFPL) technique, is an emerging technology for determining an uncooperative target’s position. The DFPL technique detects the shadowed links in a monitored area and realizes localization with the received signal strength (RSS) measurements of these links. However, most curre...

TagTrack: device-free localization and tracking using passive RFID tags

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. This technique has received much attention recently in a wide range of applications including elderly people surveillance, intruder detection, and indoor navigation. In this paper, we propose a novel localization and tracking sy...
