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 signaling 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 signaling. The registration processes in the GFAs got limitations by Multicast HMIP strategy.
