We found that in general a few active nodes are responsible for most of the information spreading. In fact, for both the
scenarios the distributions approximate a power-law (straight lines in logarithmic scale), confirming the results obtained in
smaller experiments. Moreover, by comparing the two scenarios we have that during the 09:00 pm scenario (Fig. 11-b) the
distributions of infected (and thus met) nodes are higher than those of the 05:00 pm scenario (Fig. 11-a). Finally, when the
number of active nodes is smaller, the distributions are rather flat, because each active node has the possibility of infecting
many passive nodes. This is in contrast with what happens for a larger number of active nodes, where the distribution
decreases more sharply.
