摘要

IEEE 802.11e是对IEEE 802.11标准引入QoS(服务质量)的修订草案。802.11e支持HCF (hybrid control access)，结合了EDCA (enhanced distributed channel access)和HCCA (HCF controlled channel access)两种接入方式。EDCA是一种支持优先级的分布式信道接入功能。本文讨论了EDCA中碰撞管理固有的问题。本文的主要内容如下:第一部分介绍了增强型分布式信道接入。然后我们公开冲突管理的问题。在第三部分中，我们详细地提出了修改EDCA碰撞管理的建议。

IEEE 802.11e: The Problem of the Virtual Collision Management Within EDCA

IEEE 802.11e is the draft of amendments introducing QoS (quality of service) to the IEEE 802.11 standard. 802.11e supports HCF (hybrid control access) combining two access modes: EDCA (enhanced distributed channel access) and HCCA (HCF controlled channel access). EDCA is a distributed channel access function enabling prioritization. In this paper we discuss problems inherent to collision management within EDCA. The paper organizes as follows : the first part present the enhanced distributed channel access. Then we expose the issue of collision management. In the third part we detail our proposal for a modification of the EDCA's collision management.
