| Abstract(in English) | Synchronization-free delay tomography is a scheme which can identify bottleneck links by measuring end-to-end delays between source and receiver measurement nodes in a network even when their clocks are not synchronized. The scheme selects a path between source and receiver measurement nodes as a reference path to get rid of a synchronization error, and we theoretically proved that the differential routing matrix obtained by the scheme preserves the 1-identifiability of its original routing matrix whichever path may be selected as a reference, and simulation experiments suggested that a shorter path is more preferable as a reference in terms of the k-identifiability ratio. In this article, we try to theoretically prove the preferability of the shorter path selection by investigating the distribution of absolute normalized correlation for the differential routing matrix. |
