Extended Correspondent Registration Scheme for Reducing Handover Delay in Mobile IPv6

We present a new scheme for fast binding update with correspondent nodes to expedite the handover operation of mobile nodes in Mobile IPv6 protocol supporting networks. Our scheme is an extension of the Mobile IPv6 correspondent registration process that modifies some messages exchanged between a mobile node and a correspondent node. This scheme reduces the handover latency while providing the same level of security assurances for revealing the location information to the correspondent node as in the current Mobile IPv6 protocol. We also present an extension of the scheme to multihomed mobile nodes that have heterogeneous interfaces.
