Colloquium:

Modeling Traffic on Networks as Complex Dynamical System

Monday, November 9th 2009 4 pm,
presentation-room B4.1.114, Lakeside Labs.

Prof. Dr. Bosiljka Tadic

Abstract:
        Complex structure of networks  may affect the dynamic processes on them in different ways, depending on the topological elements. On the other hand, the dynamical interactions between agents in different environments may be mapped onto networks, whose structure is varying in time. In both cases, numerical modeling offers a way to unravel structure-dynamics interdependences,specifically how the dynamical rules working at local level lead to emergent global behaviors.
        In this talk we present a numerical model of traffic of information packets, which includes minimal rules with search and queuing, and show a number of simulation results with the emphasis on the collective dynamical phenomena. We also demonstrate how the modified microscopic rules of this model can be used to study queuing and jamming effects in city traffic and
identify dynamically distinct subgraphs. Using similar methodology we analyzedata-driven networks from Blogs.
