Executive Summary

The main objective of mobility management in wireless data communication is to allow networks to search and locate (location management) mobile users while maintaining its connections (handoff management) whenever users move into a new network. Management of location and handoff divided into macromobility (for managing inter-domain network) and micromobility (for managing intra-domain network). For macromobility management, IETF has adopted Mobile IP and had performed very well for managing inter-domain mobility. However Mobile IP suffers from handover performance in intra-domain network which is inefficient for mobile user with frequent handoff.
