In this paper, we examine the cascading failure on BA networks with scale-free property based on a load redistribution rule. Assuming that the robustness is quantified by the critical threshold Tc, at which a phase transition occurs from normal state to collapse, we find the strongest robustness against cascading failures in the case of alpha =1, which is a tunable parameter in our model. We further...
How to measure node importance or find out the important node in the network has been a fundamental issue. However, since most of the existing centrality measures only take one criterion into account, they couldn't capture the specific differences among nodes and isn't in accordance with the actual circumstances. Hence, in this paper, we propose a new measure of node importance in complex networks...
In this paper, we propose an evolving small-world network model based on a local-world preferential attachment with tunable parameters. The simulation results show our model exhibits the small-world property, the scale-free structure and the disassortative mixing. Moreover, in our model, the clustering coefficient is tunable simply by changing the parameter value. Since two important mechanisms taken...
