Analysis Method of Key Vulnerable Nodes in En-route Network
In order to improve flight punctuality,ensure operational safety,and alleviate the pressure on air traffic control departments,identifying the vulnerable segments and key vulnerable nodes of the en-route network and improving them can effectively ensure the normal operation of flights and further en-hance the service level of civil aviation.Based on the en-route network data of the Guangzhou-Zhuhai airspace,the air traffic network was constructed,and three vulnerability statistical features were selected for conducting attack experiments and analyzing key vulnerable nodes.The results indicated that in the Guangzhou-Zhuhai airspace network,the nodes with higher vulnerability were mainly Conghua waypoint,Shilong waypoint,and Pingzhou waypoint.The failure of these nodes would significantly increase the vul-nerability of the region.While the vulnerability of Gaoyao waypoint,ATAGA waypoint,and Longmen way-point was relatively low,and their failure would not have much impact on the vulnerability of the whole network.
