A Temporary Binding Update in Fast Handover for Mobile IPv6

The Fast Handovers for Mobile IPv6 (FMIPv6) protocol [2] is one of the most representative extensions of the Mobile IPv6 that provides a seamless handover in mobile IP networks. However, it is also the same as in the standard Mobile IPv6 [I], the mobile node must still perform the correspondent registration including return routability procedure on every handover as soon as it gets connected to the new access router. Thus, the handover latency is considerably prolonged. This paper proposes an enhancement for FMIPv6, a temporary correspondent registration which is performed on the previous link before getting connected to the new link. Accordingly, it could significantly reduce the handover latency in the FMIPv6 protocol with the same level of security assurances as in the standard protocol. Additionally, it could remarkably reduce the buffering and forwarding packets and thereby the extra network resource consuming could considerably be reduced.
