CDS 270 -- Fall 2006
Optimization, Game and Layering in Communication Networks
Basic optimization theory, basic knowledge in communication networks.
This course discusses various equilibrium solution concepts and convergent algorithms in optimization and game theory, and their applications to network design and control. The underlying theme is “network protocols as distributed algorithms achieving various equilibria”. The objective is to introduce mathematically rigorous tools for analyzing current network protocols and designing new ones. Topics will include: Equilibrium solution concepts and convergent algorithms in optimization and game theory, the utility maximization framework of TCP congestion control, layering as optimization decomposition, path algebra and routing, contention control, power control, and distributed mechanism design for network problems.
