"Localization and Tracking in Wireless and Sensor Networks"

by

Mr. Junfeng PAN


Abstract:

Accurately tracking mobile devices in wireless and sensor networks using
radio-signal-strength (RSS) values is a useful task in robotics and
activity recognition. It is also a difficult task since radio signals
usually attenuate in a highly nonlinear and uncertain way in a complex
environment where client devices may be moving. Many existing RSS
localization systems are either inaccurate or requiring costly
calibration. How to reduce calibration effort while maintain reasonable
accuracy is still an open problem. We propose learning-based methods using
kernels and manifolds. We demonstrate the effectiveness of our algorithms
for tracking static and mobile devices in complex 2D and 3D indoor
environments using WiFi, RFID and Sensor Networks with much less
calibration effort.
