Cascading failures in communication networks with heterogeneous node functions are
studied in this paper. In such networks, the traffic dynamics are highly dependent on the …

Cascading failure occurring on complex networks has received increasing research
attentions in the past decades. In most current studies, a basic assumption is that each node …

The Internet has been studied as a typical example of real-world complex networks. In this
brief, we study the traffic performance of the Internet when it encounters a random or …

Communication/transportation systems are often subjected to failures and attacks. Here we
represent such systems as networks and we study their ability to resist failures (attacks) …

We study the robustness of several network models subject to edge removal. The
robustness is measured by the statistics of network breakdowns, where a breakdown is …

This paper reviews two problems in the security of complex networks: cascades of overload
failures on nodes and range-based attacks on links. Cascading failures have been reported …

We study the tolerance to congestion failures in communication networks with scale-free
topology. The traffic load carried by each damaged element in the network must be partly or …

Considering that not all overload nodes will be removed from networks due to some effective
measures to protect them, we propose a new cascading model with a breakdown …

Dependency groups describe different characteristics of interactions among nodes, which
provide an emerging way to explore the dynamical behaviors of complex networks. To study …

The influence of a network configuration on its vulnerability to cascade spreading is
investigated. In our model, a failure cascade is initiated by sequential disturbances that …
