| 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 based on compressed sensing, which is an emerging theory in signal/image processing for acquiring a sparse vector from a small number of linear measurements. When applied to network tomography, compressed sensing efficiently identifies links with lower communication quality from a small number of end-to-end measurements. We study a path construction scheme for the compressed sensing-based network tomography in networks with a limited number of measurement nodes. From sufficient conditions for recovering sparse vectors, we first derive a desirable property of measurement paths, and then propose a path construction algorithm based on the property. We implement the proposed algorithm in a network with two measurement nodes and evaluate the performance of the algorithm. |
