The Study And Implement Of HMIPv6 Protocol

With the rapid development of computer and network technology, information networks, especially the Internet, bring great changes in people's life. The proposed Mobile IPv6 allows a mobile node to move from one link to another without changing the mobile node's "home address". Packets may be routed to the mobile node using this address regardless of the mobile node's current point of attachment to the Internet. The mobile node may also continue to communicate with other nodes (stationary or mobile) after moving to a new link. As the limited of Mobile IPv6 protocol itself, when a mobile node is far from its home agent, delays between MN and HA will disrupt active connections every time a handoff to a new AR is performed. Eliminating this additional delay element from the time-critical handover period will significantly improve the performance of Mobile IPv6. Hierarchical mobility management for Mobile IPv6 is designed to reduce the amount of signalling between the Mobile Node, its Correspondent Nodes, and its Home Agent.In this paper, we propose a new adaptive optimization scheme integrated Fast Mobile IPv6 with Hierarchical Mobile IPv6, which enables any CNs to send packets to an MN without helps of the intermediate mobility agent. In this paper, we describe Mobile IPv6 protocol and analyzing its existing problems, firstly.In section 2, we compare the two optimization schemes proposed by IETF. We introduce an adaptive routing scheme based on FMIPv6 and HMIPv6. By this way, packets can be delivered adaptively to MN depending on its mobility.After that, it focuses on the designing and implementation of HMIPv6 protocol. This work is based on the analysing the exsiting implementation. Then complete the design of main functions, as well as the implementation. In the end, discusses its application in dual stack network.
