Model for cascading failures on complex networks based on local characteristics of nodes

Duo Wang

Abstract

To better explore the universal robustness against cascading failures on complex networks,closely focusing on the load which is the most important physical quantity that can affect the occurrence and spread of cascading failure,and dynamic process after a node fails,a cascading model with tunable parameters is proposed based on the local characteristic of a node.We obtain numerically the relation between the robustness against cascading failures on complex networks and parameters in the model,and discuss the effect of the average degree of a network for cascading failures.In addition,simulation results also are verified by the analysis of the different network graphs and the theory.
