多频带无线系统中比例公平的分布式资源分配

Distributed Resource Allocation for Proportional Fairness in Multi-Band Wireless Systems

I-Hong Hou, Piyush Gupta

摘要:

在多频带多小区自组织无线系统(诸如多信道Wi-Fi网络、3G/4G蜂窝网络中的毫微微/微微小区以及TV空白空间上的更近的无线网络)中的挑战性问题是分布式资源分配。这涉及四个组件:通道选择、客户端关联、通道访问和客户端调度。在本文中,我们提出了一个统一的框架,共同解决的四个组件与全球系统的目标,最大限度地提高客户端的吞吐量按比例公平的方式。我们的配方允许一个自然的问题分解成两个子部分。我们表明,第一部分,涉及信道接入和客户端调度,是凸的,并得出一个分布式的适应过程,实现帕累托最优解。对于第二部分,涉及信道选择和客户端关联,我们开发了一个吉布斯采样器为基础的方法,局部适应,以实现全球目标,以及从中获得快速贪心算法,实现良好的解决方案。

英文摘要:

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, we 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. Our formulation allows a natural dissociation of the problem into two sub-parts. We show that the first part, involving channel access and client scheduling, is convex and derive a distributed adaptation procedure for achieving Pareto-optimal solution. For the second part, involving channel selection and client association, we develop a Gibbs-sampler based approach for local adaptation to achieve the global objective, as well as derive fast greedy algorithms from it that achieve good solutions.
