ABSTRACT:
Disclosed herein is a method for deriving node localization information within communication networks having a plurality of nodes, which are separated by node paths. The method includes estimating the shortest path between multiple pairs of nodes in the network and constructing a matrix encompassing the estimated shortest paths. Multidimensional scaling is then applied to the matrix and the largest eigenvectors of the transformed matrix are identified. From this is constructed a relative map of the location of the pairs of nodes within the network by utilization of the eigenvectors.
