Decentralized bandwidth control subject to two-layer constraints

Abstract

This paper is concerned with the new bandwidth allocation model that considers the structural allocationconstraints. Suppose that a system is composed of finite groups of users and the bandwidth assigned toeach user and to each group of users has pre-specified upper and lower bounds. If each user is granted withthe utility function satisfying the standard continuity and concavity conditions, the existence, uniqueness,fairness and optimality properties of the Nash equilibrium point in the allocation game are studied. Toidentify the equilibrium point, an algorithm proved to converge globally is proposed and illustrated witha numerical example
