IMPLEMENTATION & ENHANCEMENT OF DESIGN PARAMETERS IN HANDOFF ALGORITHM

Abstract

The challenge in the next generation (4G) of wireless networks include the provisioning of seamless mobility across heterogeneous wireless networks, the improvement of end-to-end Quality of Service (QoS) and enabling users to specify their personal preferences. A new design provides context-awareness, smart handoff and mobility control in heterogeneous wireless IP networks. This implementation is mainly focused on Transport and Application Layer for vertical Mobility with Contextawareness. The vertical handoff decision is not only based on network characteristics but also on parameters which fall in the application and transport layers. Tramcar is tailored for a variety of different network technologies with different characteristics and has the ability of adapting to changing environment conditions and unpredictable background traffic also Tramcar allows users to identify and prioritize their preferences.
