On the Dynamics of Human Proximity for Data Diffusion in Ad-Hoc Networks
André Panisson, Alain Barrat, Ciro Cattuto +3
We report on a data-driven investigation aimed at understanding the dynamics of message spreading in a real-world dynamical network of human proximity. We use data collected by mea…
K-core decomposition of Internet graphs: hierarchies, self-similarity and measurement biases
José Ignacio Alvarez-Hamelin, Luca Dall'Asta, Alain Barrat +1
We consider the -core decomposition of network models and Internet graphs at the autonomous system (AS) level. The -core analysis allows to characterize networks beyond the d…
k-core decomposition: a tool for the visualization of large scale networks
José Ignacio Alvarez-Hamelin, Luca Dall'Asta, Alain Barrat +1
We use the k-core decomposition to visualize large scale complex networks in two dimensions. This decomposition, based on a recursive pruning of the least connected vertices, allow…
Exploring networks with traceroute-like probes: theory and simulations
Luca Dall'Asta, Ignacio Alvarez-Hamelin, Alain Barrat +2
Mapping the Internet generally consists in sampling the network from a limited set of sources by using traceroute-like probes. This methodology, akin to the merging of different sp…
Traffic-driven model of the World Wide Web graph
Alain Barrat, Marc Barthelemy, Alessandro Vespignani
We propose a model for the World Wide Web graph that couples the topological growth with the traffic's dynamical evolution. The model is based on a simple traffic-driven dynamics a…
