一种支持服务类别的无线公平调度算法

A Wireless Fair Scheduling Algorithm Supporting CoS

本文提出了一种支持服务类别的无线公平调度算法 :CoSB -WFS(基于服务类别的无线公平调度 ) .算法区分不同的服务类别并可根据其业务需要进行不同的调度 .考虑到无线信道的特殊性 ,算法引入了补偿和再分配模式 .在仿真工具OPNET上模拟了算法并得到了性能改良的结果 .

In this paper,we propose a fair scheduling algorithm called CoSB-WFS (Class of Service Based Wireless Fair Scheduling) to support QoS demands of different classes of services in wireless networks.It uses CoS index to distinguish different application level services and can use different queueing strategies for each CoS.We propose a compensation strategy and a reallocation method in the algorithm to achieve wireless fair services.We build a simple model of the algorithm in OPNET and present simulation results to show the performance improvements.
