Abstract

Throughput and fairness are conflicting performance metrics, leading to a natural tradeoff between these two measures. In this paper, we derive a generic optimization framework to obtain a relationship of system throughput and fairness, by introducing the bargaining floor. From the relationship curve, different degrees of performance tradeoff between throughput and fairness can be obtained by choosing different bargaining floors. The solutions of resource allocation obtained from the optimization framework achieve the Pareto Optimality, demonstrating efficient use of network resources.
