| 摘 要： | WMAX是一种无线城域网接入技术,主要用来解决“最后一公里”接入问题.由于“最后一公里”接入是典型的上下行链路不对称的应用,下行链路的数据量要比上行链路大得多,因此下行链路QoS机制显得尤为重要.在研究wiMAx系统下行链路QoS机制的基础上,对下行链路调度算法进行研究并进行改进.实验表明改进的算法在吞吐量和时延方面的...

| Abstract: | Worldwide Interoperability for Microwave Access(WiMAX) is a broadband wireless access metropolitan area network technology,providing a new solution to the problem of Last mile.Because Last mile application is a typical asymmetric network,compared with the uplink direction,the traffic in the downlink direction is much heavier.The downlink QoS mechanism becomes more important.On the basis of researching the QoS mechanism in WiMAX system,this paper researches scheduling algorithm of downlink direction and impr... |
