In wide area mobile networks, {em Mobile Delay Tomography} has been proposed in order to estimate delays at network components such as base stations and servers. In Mobile Delay Tomography, average delays at network components are estimated with {em Compressed Sensing} under an assumption that a {em Graph Fourier Transform}~(GFT) of delays at base stations and delays at servers are represented as sparse vectors. The graph construction scheme for GFT is an important technical issue to achieve highly accurate delay estimation. Graphs constructed based on distance among base stations, however, may increase the estimation error when the difference of average delays among neighboring base stations is large. In this article, we propose a graph construction scheme using a clustering algorithm in 3-dimensional feature space based on locations and estimated delays at base stations. We evaluate the performance of the proposed scheme with simulation experiments. |
