Motivated by recent developments in the theory of complex networks, we examine the tolerance of communication networks for intentional attacks that aim to crash the network by taking down network hubs. In addition to providing a brief survey of key existing results, we investigate two different effects that largely have been ignored in past studies. Many communication networks, such as the Internet,...
Recent researches reveal that some most important communication systems, including the Internet and the World- Wide Web (WWW), may be modeled as scale-free networks with power-law nodal-degree distributions. It is found that such networks are robust against random node/link failures yet fragile under intentional attack that takes down network nodes in a decreasing order of their degrees. Various strategies...
Being motivated by recent developments in the theory of complex networks, we examine the robustness of communication networks under intentional attack that takes down network nodes in a decreasing order of their nodal degrees. In this paper, we study two different effects that have been largely missed in the existing results: (i) some communication networks, like Internet, are too large for anyone...
