-
摘要: 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。Abstract: 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.
