无线局域网WLAN中的QoS技术研究

Study of QoS technology in wireless LAN

无线局域网WLAN已得到广泛应用,然而已经发布的IEEE 802．11协议并没有内建对QoS的支持,本文分析了基于IEEE 802．11 MAC层协议进行的各种QoS技术,重点探讨了分析了IEEE 802．11e标准对QoS的支持。对IEEE 802．11e的缺点作了简单分析。

Wireless LAN(WLAN)has widely used in communication net nowadays, but service of quality(Qos) is not supported in IEEE802. 11. In this paper, Firstly some QoS methods on IEEE 802. 11 MAC is analyzed, then the wireless LAN standards IEEE802. 11e are anatomized in details. The QoS in IEEE802. 11e is discussed emphatically. Finally, the disadvantages of IEEE802. 11e are analyzed briefly.
