Service Differentiation of IEEE 802.11e

The type of the applications for which Internet is being used has changed overthe years. Multimedia applications, Real-time applications and Game playingrequire Quality of service. IEEE has proposed IEEE 802.11e, a quality of serviceextension to the wireless LAN standard IEEE 802.11. In this paper servicedifferentiation ability of 802.11e is evaluated. Identical traffic is considered for allAccess categories to quantitatively differentiate different Access categories. Theresults indicate, 802.11e achieves service differentiation with some limitations. NS-2.26 is used for simulation.
