The impact of clustering on the transport capacity of scale-free communication networks. — •Jan Scholz1 and Martin Greiner2 — 1Frankfurt Institute for Advanced Studies, Goethe Universität Frankfurt, Ruth-Moufang-Str. 1, 60438 Frankfurt am Main, Germany — 2Corporate Technology, Information & Communications, Siemens AG, 80200 München, Germany
The efficiency of communication networks can very effectively be enhanced by optimizing the routing metrics [1]. However, there is apparent discrepancy between the performance of null models (random scale-free networks) and measured Internet topology.
A key difference between these classes of networks is clustering, which is very abundant in the Internet data, while being suppressed in random scale-free networks.
Here we investigate the influence of clustering on the increase of communication performance by adaptive routing metrics and on the robustness of the resulting weighted networks.
