Abstract
A method for positioning a collection of nodes within a wireless sensor network in which each node measures Respective Strength of Signals (RSSs), from its neighboring nodes, and channels linking regular nodes and its neighboring nodes are classified into different categories and are allocated path loss parameters accordingly. Distances separating each regular node from each of its neighboring nodes, and respective variances thereof, are estimated on the basis of the measured RSSs and the allocated path loss parameters. The positions of the regular nodes are then estimated by Weighted Least Square, optimization where the distances to be matched and the variances used for the weighting are those previously estimated.
