Performance Analysis for Optimization of Vertical Hand-Off in Hetrogeneous Wireless

Rapid growth of demand for various wireless communication services has led the industry and the researches to investigate on a new generation of telecommunication systems .One of the main objectives in designing and developing these systems is to provide the mobile user with a robust connection to different networks so that the users can move freely between heterogeneous networks while running their computing applications. Examples include cellular networks, metropolitan area networks, wireless local area networks and personal area networks. The combination of all these networks is usually called the beyond 3G (B3G) wireless networks. The B3G networking will enable mobile users to roam freely through heterogeneous networks on allIP platform. Handoff is a process, which maintains a mobile users active connection as it moves within wireless networks and vertical handoff considers handoff between different types of networks or otherwise stated between different network layers. In this paper we show how performance analysis demonstrates significant improvement that can be achieved from the proposed technique and its optimization
