This paper proposes a mobile SCTP (mSCTP) handover scheme for vertical handover between 3G wireless and WiBro networks. To evaluate the proposed mSCTP vertical handover scheme, we implement the mSCTP handover supporting system over Linux platform in which the movement of a mobile node is automatically detected and the mSCTP vertical handover is performed by the mobile node. We analyze and compare the performance of mSCTP handover and Mobile IP handover over the preconfigured testbed. From the numerical results, we can see that the handover latency of mSCTP could be much more reduced, compared to the Mobile IP handover, if the mobile node would sojourn long enough in the overlapping region between the two heterogeneous networks.
