Original Abstract

Wireless access networks of various types are the most frequently used technologies in the last mile solution i.e. bringing connectivity to the customer or end user. Wireless connections are also increasingly used inside buildings instead of cables, mainly in cases where the support of mobile users is needed. They are mostly using notebooks, organizers and PDAs for an access to company intranet by Wi-Fi technology. More often than beforewireless IP phonesare also used with Wi-Fi. The systems for measuring and controlling the quality of service are needed more and more. The 802.11b and 802.11g standards defineas one of wireless media the function called Distributed Coordination Function. It is based on the random principle and ensures rightful access to media. 802.11e contains the Enhanced Distributed Coordination Function, which can provide prioritized access for time critical traffic. The objective of the paper is to mathematically represent the Distributed Coordination Function such that it can be used as the basis of EDCF analysis.
