【摘要】 本文提出了一种有效支持QoS的IEEE802.11的分布式调度器的模型和自适应的带宽分配算法。根据在主控接入点和用户终端的各自的延时需求对满足不同的传输机制的分组流进行调度和带宽分配。这种机制能够有效减少由于实时传输带来的分组延时,增加满足不同信道负载和带宽要求的数据流的吞吐率。基于Linux的仿真结果和测试结果得到的数据基本验证了这个要求。更多还原

【Abstract】 This paper proposes a distributed-scheduler model and adaptive bandwidth allocation algorithm of QoS guarantee over IEEE802.11 system. This proposed scheme and algorithm can schedule and retransfer the packets from the different priority classers according to different delay requirements between the Master Access Points (MAP) and User Terminals (UT). This scheme effectively reduces packets delay and packets drop because of the real-time traffic, meanwhile, enhances throughput of real-time traffic satisfied with different channel load. The performance from the simulation on the Linux station is satisfied with the demand of real-time traffic over the WLAN.更多还原
