Abstract

Abstract

The basis of IEEE 802.11 wireless LAN Medium Access Control (MAC) is Distributed Coordination Function (DCF), When network load in WLAN is moderate or even higher, with DCF a station may need to defer several seconds before successful transmission. This will degrade the performance of real time applications such as MPEG-4 video stream. This paper proposes L-DCF, which is suit for real time applications, and presents mechanism for transmitting MPEG-4 video stream with L-DCF. Simulations show that this mechanism provides much less delay and jitter while obtains the same goodput and fairness.
