Distributed estimation of an unknown signal is a common task in sensor networks. The scenario usually envisioned consists of several nodes, each making an observation correlated wi...
Abstract—WiMAX with femto cells is a cost-effective nextgeneration broadband wireless communication system. Cognitive Radio (CR) has recently emerged as a promising technology to...
We study blind estimation of transmission power of a node based on received power measurements obtained under wireless fading. Specifically, the setup consists of a set of monitor...
In this work we present a calibration-free system for locating wireless local area network devices, based on the radio frequency characteristics of such networks. Calibration proc...
Abstract— A location tracking sensor network is being deployed in several buildings at the University of Michigan to help explore issues in design of pervasive environments. Mana...
