Abstract: Communication networks show the small-world property of short paths, but thespreading dynamics in them turns out slow. We follow the time evolution ofinformation propagation through communication networks by using the SI modelwith empirical data on contact sequences. We introduce null models where thesequences are randomly shuffled in different ways, enabling us to distinguishbetween the contributions of different impeding effects. The slowing down ofspreading is found to be caused mostly by weight-topology correlations and thebursty activity patterns of individuals.
