Centrality metrics of complex networks are often used to study vulnerability of networks. Thus, node-importance research are with theoretical significance and wide-spread applications. Based on neighbors average degree, this paper presents a novel approach, which combines degree of a node and the average degree of its neighbors to measure node importance. By cascading failures experiments on real-world...
The evolution of Internet topology is not always smooth but sometimes with unusual sudden changes. Consequently, identifying certain patterns of the unusual topology evolution is critical for Internet topology modeling and simulation. We analyze IPv6 Internet topology evolution in IP-level graph to demonstrate how it changes in uncommon ways to restructure Internet. After evaluating changes of average...
