Hierarchical Game and Bi-level Optimization for Controlling Network Usage Via Pricing
Résumé
Using the inherent relation between price and demand, a usage-based pricing mechanism can be an efficient tool for controlling the usage of scarce resource like bandwidth in access networks and wireless communication, where there is big competition between users. I propose here to describe my contributions in this field of network pricing and particularly dealing with hierarchical game. This kind of multi-level game is well adapted for optimizing the system manager's decision taking into account the follower game between users. We propose the use of hierarchical games for studying different networking scenarios : optimal scheduling in a DiffServ router and uplink transmissions in a CDMA cell.
