An Optimization Handover Scheme Based On HMIPv6

摘要

The process that mobile node still maintains its connectivity when moved from one access router (AR) to another access router is called handover. The handover technology is one of the most important technologies for the quality of real-time operation. In order to reduce the handover delay, Fast Mobile IPv6 (FMIPv6), Hierarchical Mobile IPv6 (HMIPv6) and Fast Hierarchical Mobile IPv6 are studied. Then, an optimization method based on HMIPv6 is advanced. On the basic of mobile anchor point (MAP), this scheme introduces the concept of regional anchor point (RAP) with the purpose of reducing the binding update messages between mobile node and home agent (HA) or correspondent node, thus lowering the handover delay.
