Abstract：In order to prevent failure condition from spreading,and avoid the phenomenon of network col-lapse effectively under the influence of propagation effect of node failure,this paper proposes a model of modified betweenness,defines initial load by controllable coefficientα,and then describes a relatively good pointα=0.6 by using the theory of degree and betweenness.Through modeling on scale?free net-work,the paper can draw a simulation conclusion by comparing the nodes under the conditions ofα<0. 6withα>0.6 subjected to attack.The simulation result shows that the node whose initial load point is low is subj ected to attack,and its survivability of corresponding network is stronger than that of the node whose initial load is high under the conditions ofα<0.6.The result is opposite under the conditions ofα>0.6.But at the conditions ofα=0.6,the survivability is comparatively good whatever what kind of node is subj ected to attack.The result shows that the viability and the survivability can increase and improve fur-thest by controlling the coefficient ofα>0.6 neighborly in real network planning.
