Distributed Estimation in Sensor Networks

Ram Rajagopal and Martin Wainwright

Institute for Transportation Studies

We study decentralized estimation problems under communication constraints. We show practical algorithms for estimating several quantities, including general M-estimators, and analyze statistical performance metrics of these algorithms. We show that our proposed decentralized strategies are optimal estimators under mild assumptions.
