The mobile Stream Control Transmission Protocol (mSCTP) can be used to support IP handover. This paper proposes an extension of mSCTP with bicasting for vertical handover across heterogeneous wireless access networks, in which the data packets of mSCTP are bicast to the old and new IP addresses in the vertical handover region. From the ns-2 simulation results, it is shown that the proposed scheme can provide better performance than the existing mSCTP.
