Study on complex networks illustrates systems of real-world in disparate realms that
incorporates a range of biological networks to technological systems and has, over the past …

As a promising approach to improve network survivability, reliability and flexibility, topology
reconfiguration is extremely important for modern networked infrastructures. In particular, for …

We study the robustness of Barabási-Albert scale-free networks with respect to intentional
attacks to highly connected nodes. Using the simulated annealing optimization heuristic, we …

Network reconfiguration is an important means of improving network invulnerability.
However, most existing network reconfiguration methods fail to consider node importance …

The threat of a malicious attack is one of the major security problems in complex networks.
Resilience is the system-level self-adjusting ability of a complex network to retain its basic …

The study of interdependent complex networks in the last decade has shown how cascading
failure can result in the recursive and complete fragmentation of all connected systems from …

The issue on optimality and robustness has become a major concern in large-scale network
systems. While a star-like centralized network surtcture is optimal in terms of the average …

There has been a considerable amount of interest in recent years on the robustness of
networks to failures. Many previous studies have concentrated on the effects of node and …

The robustness of a network is usually measured by error tolerance and attack vulnerability.
Significant research effort has been devoted to determining the network design with optimal …

In this paper, we explore the relationship between the topological characteristics of a
complex network and its robustness to sustained targeted attacks. Using synthesised scale …
