A new fairness index for radio resource allocation in wireless networks

In this paper, we investigate the measurement of fairness, discuss well known fairness notions, and propose a new utility-based framework to evaluate the degree of fairness of resource allocation schemes in wireless access networks. The proposed framework has certain desirable features. It offers clear definitions and relevant methodology, takes into account both effort and service unfairness, and can be customized for different application types with different QoS requirements. Numerical examples and case studies are given to demonstrate the effectiveness of the proposed framework.
