Heterogeneous Congestion Control

Abstract:Homogeneity of price is an implicit yet fundamental assumption underlying price based resource allocation theory. In this talk, we study the effects of relaxing this assumption by examining a concrete engineering system (network with heterogeneous congestion control protocols). The behavior of the system turns out to be very different from the homogeneous case and can potentially be much more complicated. A systematic theory is developed that includes all major properties of equilibrium of the system such as existence, uniqueness, optimality, and stability. In addition to analysis, we also present numerical examples, simulations, and experiments to illustrate the theory and verify its predictions.Bio:Dr. Ao Tang's research interests include protocol design for wireless and wireline networks, networked control and dynamical systems, optimization theory, and stochastic processes and networks.
