本文着重于IEEE 802.11媒体访问控制（MAC）的吞吐量分析。在IEEE 802.11标准中，主要接入方案被称为分布式协调功能（DCF），并且是其他接入方案的基础，例如新IEEE 802.11e MAC的点协调功能（PCF）和增强型DCF（EDCF）。由于IEEE 802.11 MAC不支持服务质量（QoS），IEEE目前正在研究增强版本的最终草案，称为IEEE 802.11e。在这个增强的标准中，支持QoS和服务差异化。研究了IEEE 802.11 MAC协议DCF/PCF在不同分组长度和不同用户数下的吞吐量和时延性能。还详细介绍了EDCF的吞吐量性能。
This paper focuses on a throughput analysis of the IEEE 802.11 Medium Access Control (MAC). In the IEEE 802.11 standard, the main access scheme is called the Distributed Coordination Function (DCF) and is the basis for other access schemes, such as the Point Coordination Function (PCF) and the Enhanced DCF (EDCF) of the new IEEE 802.11e MAC. Since the IEEE 802.11 MAC does not support Quality of Service (QoS), the IEEE is currently working on the final draft of an enhanced version known as the IEEE 802.11e. In this enhanced standard, QoS and service differentiations are supported. The throughput and delay performance of the DCF/PCF of the IEEE 802.11 MAC are presented for different packet lengths and different numbers of users. Throughput performances are also detailed for the EDCF.
