摘要:

复杂网络重要节点在遭受敌方蓄意攻击时往往会造成网络的大范围瘫痪,评估出重要节点对网络的可靠性和网络安全具有重要意义。现有的评估重要节点的中心性准则仅针对某一测度,具有局限性,因此,文章提出了一种结合现有中心性准则对复杂网络节点进行重要度排序的方法。该方法结合度中心性、中介中心性、接近中心性和特征向量中心性准则,从多角度多方位评估节点重要性。该方法借助熵权法求得每项准则的权重,避免了人为因素带来的偏差。采用多准则妥协解排序法(VIKOR)对节点的重要度进行排序,在3个典型的复杂网络上利用病毒传播模型(SI)对传播过程进行仿真。结果表明,与单一的度中心性指标、中介中心性指标、接近中心性指标和特征向量中心性指标相比,VIKOR方法能更全面更准确地排序节点的重要性。

Abstract:

When important nodes in a complex network are deliberately attacked, they will often cause a large-scale paralysis of the network. The existing centrality criterion for evaluating important nodes is only for a certain measure and it has certain limitation. Therefore, a new method combining the existing centrality criterion to rank the importance of nodes in a complex network was proposed. This method combined the criteria of degree centrality, betweenness centrality, proximity centrality and eigenvector centrality to evaluate the importance of nodes from multiple angles and directions. In this method, the entropy method is used to obtain the weight of each criterion, which avoids the deviation caused by human factors. The multi-attribute decision-making method (VIKOR) was used to sort the importance of nodes, and the virus propagation model (SI) was used to simulate the propagation process on three classic complex networks. The results show that it is consistent with the original degree index and intermediate centrality. Compared with index, proximity centrality index and feature vector centrality index, VIKOR method ranks the importance of nodes more comprehensively and accurately.

Key words: complex network, node importance, centrality criterion, entropy weight method, VIKOR model
