In Mobile IPv6, a handover latency is an important issue. To reduce the handover latency, mipshop working group in IETF has studied the fast handovers for Mobile IPv6 (FMIPv6) which creates and verifies a new care-of address (NCoA) in advance before a layer 2 handover resulting in reduced handover latency. Then the paper which reduces delay of a binding update to a home agent (HA) is emerged, called the TEBU (Tentative and Early Binding Update) scheme. This scheme can reduce handover latency, since the NCoA is registered to the HA during the layer 2 handover of FMIPv6. Additionally, if Return Routability (RR) procedure which introduces long delay is performed in advance like the TEBU scheme, the handover latency may be reduced significantly. Therefore, we propose an enhanced TEBU (eTEBU) scheme that the binding update (BU) and RR procedure are started during the layer 2 handover. The BU message and the messages for RR procedure are transferred through a fast binding update message (FBU) of FMIPv6. We perform analysis of handover latency for the performance evaluation. As a result, we found that the eTEBU scheme guarantees lower handover latency than the TEBU scheme and FMIPv6.
