A Low-Latency and Smooth Handover Scheme for Mobile IPv6

The optimization of the handover, which can minimize the handover delay and packet loss rate, is an indispensable technology in MIPv6. In this paper, a low-latency and smooth handover optimization scheme is proposed based on two main factors affecting the handover performance: duplicate address detection and binding update. A mode of duplicate address detection is introduced, in which the access router performs DAD for mobile node by querying the link-list. Besides, the strategy that mobile node sends binding update message to the home agent and the correspondent node in advance is proposed. The experiment to evaluate the performance is provided in this paper. The result shows that this approach can optimize the performance of the handover in mobile IPv6.
