Decentralized optimal flow control with constrained source rates
Seung Hyong Rhee, T. Konstantopoulis · IEEE Communications Letters · 1999
We study optimal flow control in multiservice networks, in which users (controllers) optimize their performance objectives in a decentralized manner. We adopt a model that differs from previously considered ones in that a user's strategy (viz., flow or average rate) is constrained between two numbers: those are specified by the user's quality of service (QoS) requirements or by the user's technology. Adopting the generalized power as the performance measure, we prove existence and uniqueness of the Nash equilibrium point (NEP) and suggest a simple algorithm to determine this NEP.
