An Improved Fast Handover Algorithm Based on HMIPv6

In the next generation Internet and cell networking, the mobility based on IPv6 is meant to be key technology and application. This paper analyses the mobile IPv6 and existing improved mobile IPv6, with the drawbacks showed. By study on hierarchical mobile IPv6 and the nodes' mobility and service characters, a new improved MAP choice scheme is proposed and the multicast mechanism is introduced to macro/micro mobility management. And by comparing the proposed algorithm with current HMIPv6, the excellent performance, for instance, less frequency of macro-mobility handover and more reliable communication, is showed at last.
