(English Abstract)
PCF(Point Coordination Function) of IEEE 802.11 MAC protocol is an access method oat generally has better performance under high offered load conditions. And it is also appropriate for sending data of time-limited applications. In this paper we consider the QoS(Quality of Service) enhancement method according to the change of nodes in the IEEE 802.11 WLAN. We assume that the un consists or QoS nodes and non-QoS nodes. The QoS nodes has a mechanism to support QoS. we can find the appropriate network parameters by many simulations. And the changes of network status are considered according to the number of nodes.
