Host Based Handover Approaches for Three-Tier NGN Architecture

Next Generation Networks (NGN) has a major impact on existing communication technology. The main goal of Next Generation Networks is to give a greater flexibility to the users to access the desired services from the available heterogeneous networks at anytime, anywhere vigorously with the concept of generalized mobility. Mobility management is one of the crucial functions in NGN. It is very much essential to develop heterogeneous network compatibilities and modified mobility management functionalities to provide high QoS with seamless generalized mobility for NGN system. One of the major problems of NGN is to development of new architectural concepts, protocols and functionalities for mobility management to adopt generalized mobility in order to provide seamless services to NGN users. This paper aims to develop a novel architecture for NGN and proposes host based handover approaches.
