Internet Topology

Rich-club phenomenon in the Internet

His team reported the rich-club pheromone in the Internet topology. Today, the rich-club coefficient has been widely used as a key metrics to quantify the structure of networks across a wide range of domains, including transport, social and biological systems.

Positive-feedback preference (PFP) model

His team proposed the Positive-Feedback Preference model, which is one of the most advanced Internet topology generators to date. The model provides insights into the evolution of the Internet topology, and it has been widely used in Internet research. The model can be generalised to create both disassortative and assortative networks.
