Tiivistelmä
Expanding wireless networks can be accomplished by adding Access Points (APs) which is known as infrastructure mode or without an Access Point (AP) which is known as Ad-hoc mode. Both bring about several issues, the design must be care-fully considered before it is deployed. There are many factors that are affecting the performances of Wireless Local Area Networks (WLAN) topologies designed for our network. This thesis work is about investigating and analysing the performances of two types of WLAN topologies namely; Basic Service Sets (BSSs) and Extended Service Sets (ESSs). Both Basic Service Set (BSS) and Extended Service Set (ESS) are categorised as Infrastructure mode i.e. they require AP or APs before they can function. The two types of WLAN topologies were modelled with an Optimized Network Engineering Tool (OPNET) into scenarios. There are connections between APs, switch and application server which host application of high priority. The simulation was performed with real-time video conferencing with variations in numbers of users, and data rate in megabit per seconds (Mbps). Performance metrics such as throughput, and delay were measured and closely analysed to see which connection maintain its Quality of Service (QoS).
