A dynamic and distributed domain-based mobility management method for mobile IPv6

We address mobility management for the internet protocol version 6 in mobile networks, namely mobile IPv6 (MIPv6). To correctly transfer IPv6 packets to a mobile node (MN), the MN has to update its binding to the home network while roaming away from its home network. Mobile IP networks suffer high binding update traffic from high rates of handoffs and long packet delivery delay from the large distance to the home network. In this paper, we introduce a dynamic and distributed domain-based mobility management protocol for MIPv6 to reduce the binding update and packet delivery delay and traffic. We describe the basic protocol operations and examine the performance improvement of our mobility management over the previous mobile IP mobility management method by using simulations. We show that the dynamic approach provides the optimal mobility solution for MIPv6 and the distributed approach can decentralize the network load.
