摘要：The Hierarchical Mobile IPv6 (HMIPv6) has been proposed by IETF to reduce registration control signaling. It separates micro-mobility from macro-mobility with the help of an intermediate mobility agent, called the mobility anchor point (MAP), and exploits a Mobile Node’s (MN’s) spatial locality. However, in HMIPv6, the handover process reveals numerous problems manifested by the latency in configuring a new care of address and confirmation scheme called duplicate address detection. In this paper, we proposes an Efficient Scheme Fast Handover over HMIPv6 networks. The MIPv6 mobility could be more enhanced by combining FMIPv6 with HMIPv6, in which MIPv6 is benefited from all the advantages of the respective schemes. In previous work an additional benefit by combining FMIPv6 with HMIPv6 is that the overall handover latency in HMIPv6 will be more reduced since in HMIPv6 the MN sends a location update with the with NAP, rather than the HA and CN that are typically further way. An analytical study compares the handover latency of different IP mobility management Schemes, considering the different approaches of HMIPv6 and ES-FHMIPv6. This document describes the enhanced scheme of FHMIPv6 than can reduce the latency handover of message from a certain access router to another router. The ESF-HMIPv6 is designed to be efficient with the data transport feature; we include a dual buffer in Access Point (AP) which stores the received message from Previous Access Router (PAR), the main purpose of the design scheme is to minimize the handover latency time of message transmission.
