摘要：
本文首先分析了IEEE802．11无线局域网的MAC接入机制，针对802．11e在提供QoS上的局限性，CFB的使用让EDCF机制得到了更为有效的扩展。本文在EDCF-CFB的基础上提出了一种群ACK确认机制并从理论上进行了分析。
关键词: QoS EDCF CFB 群ACK
Abstract:
This paper first analyzes the MAC access mechanism in IEEE802.11 WLAN. For the limitations of 802.11e in providing quality of services,the application of the CFB mechanism is regarded as a more efficient extension to EDCF. in the paper a group ACK mechanism based on EDCF-CFB is put forward, and its ef ficiency is analyzed theoretically.
Key words: QoS, EDCF;CFB, group ACK
