中国民用航空网络的中心化及节点攻击比较

Centrality of China aviation network and node attack comparison

以中国民用航空(CAN)网络为研究对象,应用度、紧密度、点介数和流介数四个指标对CAN进行中心化处理,判断最合适的处理方法并认定CAN网络的主要节点.其中,点介数指标对CAN网络的中心化处理效果最好,中心化程度达到96.92%.最后得出结论,中国航空网络的前五中心节点按顺序分别是北京、上海、广州、乌鲁木齐、昆明.进一步地,采用节点攻击的方法进行了验证.

This paper chooses China aviation network（CAN） as its research objective, applying respectively the four indexes of centrality degree, closeness, betweenness and flow betweenness to the centrality of CAN, thereafter determining the most appropriate treatment and thus identifying the primary nodes of CAN. It has been found that among the four kinds of treatment results, betweenness, up to 96.92% in centrality, is the best index for the centrality of CAN. The finding leads to a conclusion that the top five central nodes of CAN are Beijing, Shanghai, Guangzhou, Urumqi and Kunming in order, which has been further verified by the node attack method.
