Figure 5. Temporal network vulnerability. Each line represents the average of the size of the outgoing contact chain (OCC) through time after removal of the top 10, 250, 500, 750 and 1000 nodes ranked according to various network parameters. The colored shaded areas represent confidence interval (CI 95%).
Figure 6 shows the frequencies of OCCs resulting from the removal of 10 – 1500 nodes. When 1500 nodes were removed, selection of nodes based on degree resulted in a lower OCC sizes distribution, followed by reverse PageRank and betweenness.
