Hierarchical Mobile Ipv6 Fast Switching And Realization

As the computer network developing rapidly, wireless network and mobile network have become popular and the direction of the future network. At present, based on the next generation network of IPv6. Mobile IPv6 has been proposed to make the connection to the network incessantly while the mobile node is moving around.The idea of Mobile IPv6 can be summarized that the mobile node needn't change IP while moving around, key of which is the handover. So the latency of the handover is very important. A Model of Hierarchical Mobile IPv6(HMIPv6) mobility management was proposed to solve the problem of mobile node's bad performance when performing local movement within a domain. And the Fast Handover of Mobile IPv6(FMIPv6) was proposed to shorten the latency of handover by using the anticipative handover triggered by L2 network. After analyzing Mobile IPv6, HMIPv6 and FMIPv6, the proposal of Fast Handover for Hierarchical MIPv6 (F-HMIPv6) was tabled, in which the mobile node shortened the handover latency by responding to the anticipative handover. The principles, architectures, data flows and the operations of the F-HMIPv6 were decribed in detail, and a testbed was set up to implemented the F-HMIPv6.
