HMIPv6 draws lots of attention in recent years for providing an efficient handoff and reducing the signaling overhead. HMIPv6 employs MAP(Mobility Anchor Point) in order to minimize signaling overhead and to support local mobility management. HMIPv6 provides an outstanding mobility management in the network environment with frequent micro-handoff but incurs higher signaling cost than MIPv6 in case of macro-handoff. In this paper, we propose the FMHS(Fast Macro-Handover Scheme) for efficient macro-handoff in HMIPv6 networks. The FMHS reduces binding update cost, in which a MN sends binding update(BU) message including the newly obtained RCoA to the previous MAP instead of its own home agent(HA) where several MAPs exist in the administration domain. The FMHS reduces about 56% binding update cost and shortens macro-handover delay compared to HMIPv6.
