Research of an Optimized Mobile IPv6 Real-time Seamless Handover Technology

Mobile IPv6 provides mobility support for hosts connecting to the Internet, it solves addressable problems of the mobile terminal, and the mobile terminals can obtain network services without changing IP addresses. But MIPv6 can introduce substantial network expenses and lengthy handoff delay during the mobile handover process, meanwhile, more and more delay sensitive real-time applications require a packet lossless QoS guarantee during a handoff. It proposes an optimized seamless handover mechanism on the basis of existing handoff methods in this paper, it builds on top of the hierarchical method and the fast handoff mechanism and adopts a decision engine-based dynamic distributed architecture, at last it verifies that using this new handoff scheme can reduce packet loss and handoff delay efficiently and improve handoff efficiency by doing simulation experiments.
