Modelling and simulation of IEEE 802.11a wireless local area networks using SDL

Abstract

In this paper we present a comprehensive and standalone SDL-based model for performance analysis and planning of IEEE 802.11a wireless local area networks (WLANs). It is based on the obtainable behavior code from the IEEE 802.11 standards committee. We have made all the necessary improvements to provide efficient way for simulation of the IEEE 802.11a based WLAN. Our performance model encompasses the entire 802.11a MAC and PHY functionalities. It is further developed with several alternative types of channels. The simulation model is validated via extensive simulation scenarios regarding the WLAN performances. We verified that the developed simulation model for 802.11a networks can be efficiently used in analysis, planning and optimization of 802.11a wireless networks for different types of services and for different environments
