Distributed Resource Allocation for Proportional Fairness in Multi-Band Wireless Systems
A challenging problem in multi-band multi-cell self-organized wireless systems, such as multi-channel Wi-Fi networks, femto/pico cells in 3G/4G cellular networks, and more recent wireless networks over TV white spaces, is of distributed resource allocation. This involves four components: channel selection, client association, channel access, and client scheduling. In this paper, the authors present a unified framework for jointly addressing the four components with the global system objective of maximizing the clients' throughput in a proportionally fair manner. Their formulation allows a natural dissociation of the problem into two subparts.
