Device-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 able to trade complexity for accuracy by simply changing the number of deployed devices. The presentation is validated by an indoor experimental study.
