802.11WLAN中一种基于循环队列的分布式公平队列调度算法

A Round Robin Based Distributed Fair Queuing Algorithm for IEEE 802.11 WLAN

该文在无线局域网现有的802.11 MAC层访问机制的基础上,运用循环队列的思想提出了一种完全分布式的队列调度算法,该算法通过修改802.11的MAC层中的DCF(Distributed Coordination Function)子协议,实现了在分布式环境下控制802.11节点的公平访问无线链路资源的目的.文中通过仿真对算法进行了分析和研究,仿真结果表明该方法可以在一定范围内实现公平队列调度。

This paper presents a novel round robin based fully distributed fair queuing algorithm for IEEE 802.11 WLANs. The proposed algorithm in this paper achieves fair scheduling in a distributed environment by doing a small modification to the distributed coordination function of the IEEE 802.11 MAC protocol. Simulation results show this algorithm is effective.
