Proposal of NS2 Simulation Based Study of IP Multimedia Applications on IEEE 802.11 Based Network Comprising Virtual Server Arrays
The market for IEEE 802.11 Wireless Local Area Networks (WLANs) continues to grow at a rapid pace. Business organizations, educational institutions and universities are value the simplicity and scalability of WLANs as well as the relative ease of integrating wireless access with existing network resources. WLANs support user demand for seamless connectivity, flexibility and mobility. But current WLAN systems suffer difficulties due to the increasing expectations of end users and unstable bandwidth delay boundary demands from new higher data rate services, such as High-Definition TeleVision (HDTV), video teleconferencing, multimedia streaming, Voice over IP (VoIP), file transfer and online gaming.
