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

Table 5

Evolution of the weighted efficiency and the LCC of the large local components after their isolation due to attacks based on weighted betweenness. We also report the order of isolation of the components. ωi is the weighted efficiency before the attack based on weighted betweenness. ω is the weighted efficiency after the separation. λ is the largest connected component size after the split. ρ is the fraction of top weighted betweenness nodes removed from the world air transportation network to isolate the component. γ is the order in which the components are isolated. Globally, after their isolation, the efficiency of the LCC does not change much. Some LCCs are even more efficient.
