As one of the critical infrastructure network, the air transportation network provides the fastest way for millions of people to travel around the world every day. At the same time, it is also responsible for the world-wide propagation of infectious diseases such as the influenza and SARS. In this project, we study and analyze the worldwide air transportation network. In particular, we will build a network which consists of more than 3000 airports and establish links between pairs of airports that are connected by non-stop passenger flights. Then, the impact of link-removal on both the epidemic spreading and the centrality betweenness of the most central airports are investigated. Our result is that the link between Changi Airport and Newark Liberty International Airport, USA (SIN-EWK) and London Heathrow Airport, UK (SIN-LHR) are among the most suitable links for removal. We found that single link removal has no significant impact on reducing epidemic spreading on Changi Airport, Singapore.
