The Study Of Load Redistribution Under Cascading Failures On Complex Networks

With the development of economy and technology, people’s life has entered the network era. Cascading failure in network is produced accompanied by the rapid development of the network, closely related to our production and life.the failure will seriously affect a wide range of people’s production and life, and bring irreparable damage.This paper research the problem on cascading failures in single complex network and interdependent complex network,based on edge failures.Researching methods is that making a model of cascading failures in networks and then simulating by Matlab software and analyzing the simulation result.We put forward a new edge spare capacity proportion based on load allocation mechanism of cascading failure model in the research of a single complex network cascade failure.Making a comparison between the cascading failure model and transmission model In Matlab simulation. Compared to two kinds of cascading failure model under the network stability through the deliberate attack and random attack in the network edge. Building a new network cascading failure model in the study of cascading failure associated network.The failure propagation includes four stages of the model and solve three key problems.The first problem is building the connections between two network, the second problem is determing the collapse strategy between two networks, the last problem is that the failure of network transmission mechanism between the network and how to determine the failure propagation mechanism, and how to link two transmission mechanism. We discuss the effect on the stability of the different network structure、attack method and different network correlation on the network., and correlation of two different network cascading failure model WS-WS affiliate network stability is analyzed. Through the above analysis, this paper put forward several proposals to the network security and stability...
