Abstract
This paper presents an 802.11b Distributed coordinated function (DCF) approach that specifically concentrates on the multi-rate WLAN. In this approach we assume a saturated condition where every node in the network have a packet to transmit at any time and also a clear channel condition in which there is no hidden terminal in the network. This saturation throughput and delay are used to analyze the DCF. This work shows that in a slowly changing channel a smaller Sm and larger Fm for the ARF protocols needs to be set and used for better network performance.
