Abstract

The IEEE 802.16 standard is currently one of the most interesting broadband wireless access. One key issue of mesh networks is the MAC (medium access control) layer. In this paper we analyze the coordinated distributed scheduling scheme (CDS) of the standard IEEE 802.16. Since some fundamental parameters in this scheme has been left un-standardized, we focus on the dynamic setting of these parameters in order better performance in terms of throughput and average end-to-end data packets delay to be obtained. The standard describes a data scheduler in a general way, based on a three-way-handshake mechanism, but details about data scheduler scheme have been left un- standardized. In order to obtain a better evaluation in terms of performance of the control schedule, we implemented a simplified data scheduler and we show how this simplified data schedule allows smaller data delay transmissions to be realized.
IEEE 802.16协调分布式调度程序参数设置的动态方法
IEEE 802.16标准是目前最受关注的宽带无线接入标准之一。网状网络的一个关键问题是MAC(介质访问控制)层。本文分析了IEEE 802.16标准下的协调分布式调度方案(CDS)。由于该方案中的一些基本参数没有标准化,因此我们将重点放在这些参数的动态设置上,以便在吞吐量和平均端到端数据包延迟方面获得更好的性能。该标准以一种通用的方式描述了一个基于三次握手机制的数据调度器,但是关于数据调度器方案的细节还没有标准化。为了更好地评估控制调度的性能,我们实现了一个简化的数据调度程序,并展示了这个简化的数据调度如何允许实现更小的数据延迟传输。
