This project continues a study of the quality of service provision problem in noncooperative network environments where applications or users are assumed to behave in a selfish way. We have formulated a model of QoS provision in noncooperative network environments and presented an initial game-theoretic analysis of its properties and equilibria. Several questions remain that need to be studied about these equilibria. In particular, the assumption that the satisfaction curve of customers/applications is a unit-step needs to be removed. Furthermore, using adaptive conditioning of network parameters to jog the system into or out of equilibria has to be studied.
