无线蜂窝网络目前所采用的机会调度算法在公平性方面存在缺陷。为解决该缺陷,该文提出了一种适用于无线数据网络的基于多用户分集效应的相对比例公平调度算法。不仅可以通过改变参数来调节系统吞吐量,保证系统性能;而且可以保证各用户之间的公平性,满足不同用户的服务质量要求。仿真实验表明,该算法可以在不同用户之间提供公平的服务,而且能兼顾系统吞吐量和用户服务质量的要求。 The opportunistic scheduling algorithms currently used in wireless cellular networks are flawed in terms of fairness. In order to solve this problem, this paper proposes a relative proportional fair scheduling algorithm based on multi-user diversity for wireless data networks. Not only by changing the parameters to adjust the system throughput, to ensure system performance; but also to ensure fairness among users, to meet the quality of service requirements of different users. Simulation results show that this algorithm can provide fair service between different users, and can meet the requirements of system throughput and user service quality.
