无标度网络具有对蓄意攻击脆弱性的特性,分析发现hub节点的存在是这一问题产生的根源.文章给出了通过对网络增长过程中加入随机边,促使hub节点作用退化的PBA模型.实验和分析表明该模型有效提高了对蓄意攻击的鲁棒性.
Scale-free network has deliberate attack vulnerability.Analysis shows that the presence of hub nodes is the main cause of this problem.In this paper,PBA model is given by adding random edges during scale-network growth to make hub nodes degrade.Experiments and analysis show that the model is effective to improve the robustness of deliberate attacks.
