Abstract
Abstract — With the deployment of IEEE 802.11 networks, supporting real-time traffic with stringent Quality of Service (QoS) requirements on these networks becomes a critical issue. In this paper we propose two new media access schemes, namely Dynamic Point Coordination Function (DPCF) and modified DPCF (DPCF2). These can improve the capacity for Voice over IP (VoIP) traffic by up to 20 % in IEEE 802.11b networks. We will show how we can also achieve a drastic improvement in the end-to-end delay with mixed VoIP and data traffic. Delay is kept around 100 ms in heavily loaded traffic conditions with an average value under 60 ms in normal traffic conditions. I.
