| 摘 要： | 由于快速分层切换技术FHMIPv6将FMIPv6和HMIPv6切换技术结合起来,因此,在层次移动管理模型中部署快速切换时具有两种技术所具有的优点,可使切换延时进一步减少。文中通过对FHMIPv6的研究发现,其切换过程中DAD重复地址检测过程严重影响了切换性能,因此提出了基于IPv6组播的M-FHMIPv6切换技术。理论分析证明,M-FHMIPv6能有效减少DAD检测过程和各种信息交互的延迟。通过NS2实验仿真进一步说明:改进的M-FHMIPv6方案能减少切换延迟,平滑切换过程。

| Abstract: | The fast handover for hierarchical MIPv6 technology(FHMIPv6) combined with FMIPv6 and HMIPv6 has an advantage of less handover delay.In the study of FHMIPv6,we find that the procedure for duplicated address detection(DAD) badly affects the performance of handover.Inspired by this phenomenon,a new technology named multicast-fast handover for hierarchical MIPv6(M-FHMIPv6) has been put forward based on IPv6 multicast.The M-FHMIPv6 can effectively reduce the handover delay caused by DAD in information exchange theoretically.Furthermore,the simulator in NS2 proves that M-FHMIPv6 can reduce handover delay and smooth handover process. |
