Information spreading in dynamic graphs
We showed how a technique used to analyse the flooding completion time in the case of a special class of random evolving graph model, that is, the edge-Markovian model, can be used in order to prove that the flooding completion time of a random evolving graph is bounded by , where intuitively (1) is the smallest time necessary for the rising of a giant component, (2) is the diameter of the giant component, and (3) is the time required for the nodes outside the giant component to eventually get an edge connecting them to the giant component [30] . Then, based on this result, we developed a general methodology for analysing flooding in sequences of random graphs and we applied this general methodology to the case of power-law evolving graphs (that is, sequences of mutually independent random graphs such that the number of nodes of degree distributes like for some ), and to the case of an arbitrary given degree distribution.
