Robustness Analysis of the Regional and Interregional Components of the Weighted World Air Transportation Network

Figure 4

The figure at the left represents the fraction of nodes in the LCC of the large local and global components as a function of the fraction of removed nodes under a strength attack on the world air transportation network. We also represent the LCC of the world air transportation network in this situation. The Europe-Russia component and the global component are less sensitive to the attack. The figure at the right shows the weighted efficiency of the large local and global components as a function of the fraction of removed nodes under a strength attack on the world air transportation network. We also represent the weighted efficiency of the world air transportation network in this situation. Efficiency decreases at a high rate as the fraction of top strength nodes removed increases. Furthermore, the North America-Caribbean and Africa-Middle East-Southern Asia components appear to be the most vulnerable.
