Distributed Cooperative Localization of Wireless Sensor Networks With Convex Hull Constraint

Free registration required

Executive Summary

Localization of wireless sensor networks is aimed at determining the positions of all sensors in a network, usually given a few connected anchor nodes' positions and certain relative measurements, where the latter could be pairwise distance measurements among directly connected neighbors as considered in this paper. In this paper, the authors investigate the neighborhood collaboration based distributed cooperative localization of all sensors in a particular network with the so-called 'Convex hull constraint': all nodes in such a network are either connected position-known anchors or sensors to be localized, and every sensor is inside the convex hull of its neighbors.
