Wireless local area networks (WLANs) have been around for a long time but only recently have they become popular. Despite the fact that Wireless LANs have achieved a tremendous amount of growth in recent years, the performance is very poor. Hence, multimedia wireless network QoS support has become one of the most important researches. In order to improve the poor performance of existing system, QoS features and MAC enhancements are needed in the upcoming 802.1 le standard. This project aims to evaluate the performance of Wi-Fi systems with and without QoS, and quantify how well the new enhancement can support applications that require certain QoS guarantees. A thorough research on the IEEE802.11 standards is necessary to the success ofthis project, as well as an immaculate and extensive study on the QoS performance ofthe network. All the studies and evaluation is being done with a simulation using OMNeT++. The project requires knowledge of the WiFi architecture, C++ programming language, setting up simulation of a network in OMNeT++, andthen evaluating theQoS performance.
