| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Delay tomography means to estimate internal link delays in a network by means of measuring end-to-end path delays. In this paper, we focus on a delay tomography scheme based on compressed sensing which can effectively identify bottleneck links. So far, delay tomography has burdened source and receiver measurement nodes with clock synchronization between them in order to compute the end-to-end path delays, while we propose a synchronization-free delay tomography scheme. The proposed scheme selects a path between source and receiver measurement nodes as a reference path, which results in a loss of equation in a conventional delay tomography problem. However, by utilizing compressed sensing, the proposed scheme becomes robust to the loss. Simulation experiments confirm that the proposed scheme works comparable to a conventional delay tomography scheme in networks with no clock synchronization between source and receiver measurement nodes. | |
