Abstract:

To solve the problem that the duplicate address detection (DAD) in hierarchical mobile IPv6 (HMIPv6) links too time consuming,a handover algorithm based on fast DAD mechanism for HMIPv6 was proposed.By introducing the IP address allocation management (IAAM) module to establish the DAD-lookup and initiative address-generation mechanism,the proposed algorithm can greatly speed up the DAD course and be implemented easily.Simulation results showed the HMIPv6 optimized by the algorithm (F-DAD-HMIPv6) could reduce intra-domain handover delay and inter-domain handover delay to 202ms,339ms respectively and was superior to MIPv6 and HMIPv6.

Key words: hierarchical mobile IPv6, IP address allocation management, duplicate address detection, handover delay
