WiMAX中不同调度算法的性能评估

Performance Evaluation of Different Scheduling Algorithms in WiMAX

Ala'a Z. Al-Howaide, Ahmad S. Doulat, Yaser M. Khamayseh

摘要:

全球微波接入互操作性(WiMAX)网络被期望成为主要的宽带无线接入(BWA)技术,其提供诸如数据、语音和视频服务的若干服务,包括不同类别的服务质量(QoS),其又由IEEE 802.16标准定义。WiMAX中的调度是最具挑战性的问题之一,因为它负责在所有用户之间分配网络的可用资源,这导致了构造和设计高效调度算法的需求,以提高网络利用率,增加网络吞吐量,并最小化端到端的延迟。在本研究中,我们提出了一个模拟研究,以衡量在WiMAX中的几种调度算法,即严格优先级算法,轮循(RR),加权轮循(WRR),加权公平调度(WFQ),自时钟公平(SCF),区分服务算法的性能。

英文摘要:

Worldwide Interoperability for Microwave Access (WiMAX) networks were expected to be the main Broadband Wireless Access (BWA) technology that provided several services such as data, voice, and video services including different classes of Quality of Services (QoS), which in turn were defined by IEEE 802.16 standard. Scheduling in WiMAX became one of the most challenging issues, since it was responsible for distributing available resources of the network among all users; this leaded to the demand of constructing and designing high efficient scheduling algorithms in order to improve the network utilization, to increase the network throughput, and to minimize the end-to-end delay. In this study, we presenedt a simulation study to measure the performance of several scheduling algorithms in WiMAX, which were Strict Priority algorithm, Round-Robin (RR), Weighted Round Robin (WRR), Weighted Fair Queuing (WFQ), Self-Clocked Fair (SCF), and Diff-Serv Algorithm.
