A new cascading model on scale-free network with tunable parameter

摘要：

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 ofα=1,which is a tunable parameter in our model.We further discuss the correlations between the average degree<k>of BA network and Tc ,and draw the conclusion that Tc has a negative correlation with the average degree <k>,i.e.,the bigger the value of <k>,the smaller the critical threshold Tc.These results may be very helpful for real-life networks to avoid cascadingfailure-induced disasters.
