IEEE 802.11ac-based Outdoor Device-free Human Localization

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...

Nonlinear Optimization-Based Device-Free Localization with Outlier Link Rejection

Device-free localization (DFL) is an emerging wireless technique for estimating the location of target that does not have any attached electronic device. It has found extensive use in Smart City applications such as healthcare at home and hospitals, location-based services at smart spaces, city emergency response and infrastructure security. In DFL, wireless devices are used as sensors that can...

Multichannel RSS-based Device-Free Localization with Wireless Sensor Network

RSS-based device-free localization (DFL) is a very promising technique which allows localizing the target without attaching any electronic tags in wireless environments. In cluttered indoor environments, the performance of DFL degrades due to multipath interference. In this paper, we propose a multichannel obstructed link detection method based on the RSS variation on difference channels. Multi...

Device-Free Indoor Localization Based on Ambient FM Radio Signals

This paper presents the concept of device-free indoor localization using only a passive receiver and ambient FM radio signals. Experimental results based on empirical measurements demonstrate the feasibility of the proposed approach. The authors also evaluate fine-grained localization performance of the system, its temporal stability, and highlight the role of frequency diversity for passive lo...
