Abstract(in English) | Network tomography is an inference technique for internal network characteristics from end-to-end measurements. In this article, we consider network tomography for estimating packet loss rates in a wireless multihop network over a location-dependent wireless channel, and propose a new network tomography scheme based on graph Fourier transform, which is dened by eigenvectors of the graph Laplacian matrix. In the location-dependent wireless channel, a node state vector, representing packet loss rates of nodes, can be approximated to a sparse vector in the graph Fourier transform domain. The proposed scheme estimates the graph Fourier transformed node state vector with compressed sensing. We evaluate the performance of the proposed scheme with simulation experiments. |
