  Abstract

This paper analyzes the throughput performance of CSMA/CA-based DCF protocol for both infrastructure mode and ad-hoc mode under fading channels with payload size at the MAC layer in the 802.11a wireless LAN. The number of stations n is assumed to be fixed and each station always has packets for transmission. In other words, we operate in saturation conditions. In the ad-hoc mode, the nodes are mobile with typical speed and carrier frequency. Channel fading is slow and correlated, which usually causes burst errors in a packet. In such a channel, FEC or interleaving may not be effective and adapting frame length to the channel is a good scheme to improve performance.
