With the successful development of IEEE 802.11 based wireless LAN(WLAN), applications with QoS requirements are asked to be provided in WLANs. Because of their delay restrictions, realtime applications should work under unsaturated conditions. In this paper, firstly, traffic models for different kinds of applications are proposed to convert the unsaturated system into an equivalent saturated system and calculated out the queueing delay in the sender buffer; then, a new analysis model is… CONTINUE READING
