3G interworking with WLAN QoS 802.11e

Seamless interconnection with WLAN 802.11 and 3/4G technology is essential for the future wireless environment. Supporting quality of service is one of the most important issues in 3/4G. In this paper the WLAN QoS standard IEEE 802.11e draft is studied at the point access network for 3G traffic classes. 802.11e is compatible with the layer 2 802.11p standard and resembles DiffServ QoS functionality that is proposed to be one of the applied QoS standards in 3/4G networks. We analyze how well 802.11e's QoS properties perform under the different kind of simulation scenarios when packet sizes and channel error rates are varied.
