In wireless/mobile networks, users freely change their service point while they are communicating with other users. In order to support the mobility of mobile nodes, Mobile IPv6 (MIPv6) is proposed in IETF, in which an MN must inform its home agent the binding of its home address and the current care-of address (CoA). The home agent forwards packets to CoA when it receives packets for the MN. There is a significant problem in MIPv6 due to its inability to support micro-mobility cause by long delay and high packet loss during handover. Hierarchical mobile IPv6 (HMIPv6) is proposed to separate mobility into micro-mobility (within one domain) and macro-mobility (between domains). HMIPv6 introduced a new protocol element called Mobility Anchor Point (MAP) to manage the mobility. HMIPv6 can reduce the delay and the amount of signaling during handover. However HMIPv6 only improves micro mobility problem where the significant delay still occurs in macro mobility management. Duplicate address detection and the transmission time during the handoff operation could cause high delays. This paper considers handover operations. By simulations, we show that the proposed scheme can realize low handoff delay and packet loss during handover.
