IEEE 802.11 WLAN is used widely because of the flexibility of Wireless LAN. Subscribers hope that the Wireless LAN can supply Real-time application as the wired network, for example, video and voice service, these require service differentiation in networks. Service differentiation at the IP layer is useless without support of that in lower layers. This support is even more critical in wireless networks because of its instability and limited bandwidth. This paper aims at the promotion of data stream transfer through research in TCP/UDP transfer over MAC layer supported by EDCF. Applications impose requirements on communication parameters, such as data rate and delay. In this paper we present ideas to provide service differentiation support for 802.11e and compare it with the legacy DCF of IEEE802.11 by simulation, and analyze the result in performance of the schemes with TCP and UDP flows.
