Abstract
People who use wireless device for Internet are gradually increasing. For mobility service, MIPv6 has been proposed by IETF. With no restriction on node's geographical location, mobility is provided to a mobile node (MN) by MIPv6. However, MIPv6 has critical points, such as handover latency resulting from movement detections, IP address configurations and location updates which is unacceptable in real-time application. To make up for it, hierarchical MIPv6 (HMIPv6) has been proposed. HMIPv6 guarantees to reduce handover latency, because the MN only registers the new addresses at mobility anchor point (MAP) when the MN moves around access routers in the same MAP domain. HMIPv6 still has packet loss problem when the MN moves from one MAP to another. In this paper, we propose an efficient handover scheme which reduces packet loss when the MN moves between MAP domains. We adopt the fast handover method from FMIPv6 (fast MIPv6) for proposed scheme.
