A NOVEL COHESIVE AND SERVICE DRIVEN METHODOLOGY FOR AUGMENTING THE VERTICAL HANDOVER PERFORMANCE IN HETEROGENEOUS WIRELESS NETWORKS

ABSTRACT Due to the mounting requirement for anytime, anywhere network services, we need to integrate diverse kinds of wireless networks. For assisting this integration, the mobile users should be allowed to freely move across networks Keywords: wireless networks, proxy mobile IPv6, mobility management, vertical handover, media independent localized routing. INTRODUCTION The evolution of wireless technologies has led to different groups of wireless cellular systems which can be referred as NGN (Next Generation Networks), e.g., 2G, 2.5G, 3G, etc
