This paper presents a design procedure for access and congestion control in communication networks. Motivated by an analysis of the characteristics of communication networks, the proposed approach makes use of model-based control methodologies, i.e. Internal Model Control, Model Reference Control and the Smith's principle. The design procedure is then applied to the problems of access control in satellite...
We present a framework for designing delay- independent end-to-end congestion control algorithms, where each end-user may have a different utility function. We only require that utility functions are strictly increasing. In this framework, we design an algorithm that maximizes the minimum utility value in the network, that is, the resulting resource allocation is utility max-min fair. To achieve this,...
We study in this paper a noncooperative approach for sharing resources of a common pool among users, wherein each user strives to maximize its own utility. The optimality notion is then a Nash equilibrium. First, we present a general framework of systems wherein a Nash equilibrium is Pareto inefficient, which are similar to the 'tragedy of the commons' in economics. As examples that fit in the above...
