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...
متن کاملTrajectory-Based Indoor Device-Free Passive Tracking
Device-free passive (DfP) localization is proposed to localize human subjects indoors by observing how the subject disturbs the pattern of the radio signals without having the subject wear a tag. In our previous work, we have proposed a probabilistic classification based DfP technique, which we call PC-DfP in short, and demonstrated that PC-DfP can classify which cell (32 cells in total) is occ...
متن کاملDevice-Free Indoor Localization for AAL Applications
We present a device-free localization method oriented to Ambient Assisted Living applications. The system exploits the received signal strength (RSS) measured by fixed wireless communications devices, whose position is known a priori, in order to localize a person in the transmission coverage area. The proposed localization system is passive, by not requiring the user to wear anything, and is a...
متن کاملA Review on Device-Free Passive Indoor Positioning Methods
There is an increasing need for unobtrusive positioning systems in smart homes and assisted living environments. This review presents the main technologies used for device-free passive indoor positioning, including pressure sensors, thermal infrared sensors, sound source localization, ultrasound, radio frequency, infrastructure-mediated sensing and electric-field-based methods. In addition, it ...
متن کاملMultimodal Indoor Device Localization
In this thesis we present a method of indoor localization and tracking that combines multiple sensor measurements to remove dependence on any one information source. A two-step process is proposed that performs an initial localization estimate, followed by particle filter based tracking. Initial localization is performed using WiFi and image observations. For tracking we fuse information from W...
