Original Abstract

The IEEE 802.11 standard defines access categories (AC) and differentiated medium access control mechanisms for wireless local area networks. The preferential or deferral treatment of frames is achieved using configurable Arbitration Inter-Frame Spaces (AIFS) and customizable Contention Window (CW) sizes. In this paper, we address the problem of determining when a station, being a part of wireless communication, will access the medium. We present an algorithm calculating the probability of winning the contention by a given station, characterized by its AIFS and CW values. The probability of collision is calculated by similar means. The results were verified by simulations in Matlab and OPNET Modeler tools. We also introduce a web applet implementing and interactively demonstrating the results.

Standard IEEE 802.11 definuje kategorie přístupu (AC) a diferencované mechanismy řízení přístupu k médiu pro bezdrátové lokální sítě. Preferenční způsob zacházení je dosaženo použitím parametrů AIFS a CW. V tomto článku se zabýváme vyhodnocením, kdy stanice, která je součástí bezdrátové komunikace, získá přístup k médiu. Představujeme zde algoritmus, který vypočítává pravděpodobnost výhry přístupu k médiu pro danou stanici, na základě AIFS a CW hodnot. Pravděpodobnost kolize se vypočítá odobným způsobem. Výsledky byly ověřeny simulací v Matlabu a OPNET Modeler. Rovněž představujeme webový applet, jež implementuje a interaktivně demonstruje výsledky.
