In this paper, we propose an algorithm to estimate 2D shapes and positions of obstacles such as buildings using GPS and wireless communication history of mobile nodes. Our algorith...
Localization is a fundamental operation for many wireless networks. While GPS is widely used for location determination, it is unavailable in many environments either due to its h...
As an alternative to ad hoc wireless sensor networks, we propose to utilize the mobile devices that are carried by people who walk along the site on which the sensors are deployed....
— Until recently, the problem of localization in wireless networks has been mainly studied in a non-adversarial setting. Only recently, a number of solutions have been proposed t...
A distributed adaptive algorithm to estimate a time-varying signal, measured by a wireless sensor network, is designed and analyzed. The presence of measurement noises and of packe...
