Performance Evaluation of Heterogeneous Networks for Various Applications Using OPNET Modeller

Abstract

Wireless networking is an attractive networking solution due to its flexibility, mobility and ease of installation without damaging the furnishing of buildings (this factor play most important role in situations where buildings are of higher heritage importance).Wireless networks such as WLAN, WIMAX, UMTS etc are growing rapidly and there is a strong need to support multimedia applications. Wireless networks are becoming more and more popular in recent years from digital cellular telephony up to satellite broadcasting. With the increasing demand and wireless services, users of wireless networks now expect Quality of Service (QoS) and performance comparable fixed networks. Internetworking of network is done to support 4G and provide a boon to next generation wireless communication system. It also provide anywhere anytime connectivity to users as mobile moves from one place to another. Also Providing QoS requirements like good throughput and minimum access delay are challenging tasks.
