Executive Summary

In this paper, the authors propose a new approach to sensor localization problems, based on recent developments in machine leaning. The main idea behind it is to consider a matrix regression method between the ranging matrix and the matrix of inner products between positions of sensors, in order to complete the latter. Once, they have learnt this regression from information between sensors of known positions (beacons), they apply it to sensors of unknown positions. Retrieving the estimated positions of the latter can be done by solving a linear system. They propose a distributed algorithm, where each sensor positions itself with information available from its nearby beacons. The proposed method is validated by experimentations.
