An Analytical Model to evaluate the Approaches of Mobility Management

Now a day’s efficient mobility management for mobile users in wireless networking is a crucial issue. To maintain global mobility in IP networking the Mobile internet protocol has been proposed. To reduce the signalling traffic related to the Mobile Terminals (MTs) registration with the Home Agents (HAs), whenever their Care-of-Addresses (CoAs) change several mobility management strategies have been proposed. And for registration process they use different Foreign Agents (FAs) and Gateway FAs (GFAs) hierarchies. For better and enhanced -mobility MTs, the Hierarchical MIP (HMIP) and Dynamic HMIP (DHMIP) strategies localize the registration in FAs and GFAs, yielding to high-mobility signalling. The registration processes in the GFAs got limitations by Multicast HMIP strategy. And it provides lowest mobility signalling delay compared to the HMIP and DHMIP approaches to achieve high-mobility MTs. However, for frequent MT mobility it is a resource consuming strategy. Hence, To evaluate the mean signalling delay and the mean bandwidth per call according to the type of MT mobility we propose an analytic model. In all the studied cases the performance of MHMIP is more and accurate as compared to the DHMIP and MIP strategies .In this paper we are proposing the analytic model that allows the mobility management.
