Novel Scheme for Technology of Handover in Mobile IPv6

Mobile node will produce handover when it moves between two different sub networks. The technology of handover of the mobile node is one of the key problems of guaranteeing the quality of service of the real-time business. Now, IETF is developing fast handover and hierarchical mobile IPv6 to provide handover mechanisms for mobile IPv6. Based on the principle of the two technologies, this paper introduces some progress, and a new fast handover scheme under hierarchical mobile IPv6 is presented.
