Abstract [en]

This paper proposes a new solution approach for the simultaneous mobility issues in seamless handover. An alternative scheme is designed to minimize handover latency between two different networks with location management support while simultaneous handover occurs. One of the most emerging techniques in recent research projects for mobility management is mobile Stream Transmission Control Protocol (mSCTP). The multi-homing feature of Stream Control Transmission Protocol (SCTP) and dynamic address reconfiguration (DAR) extension of SCTP are applied in the proposed solution to achieve improved seamless performance. We used an additional Location Server (LS) to ensure location management between simultaneously moving mobile nodes (MNs) while simultaneous handover occurs. This research is dedicated to design a new model of simultaneous mobility based on 'Step-length' and the implementation of the model i.e., mSCTP with LS to solve the simultaneous mobility issues. 'Step-length' is defined as the random distance travelled by the simultaneously moving MNs in each step when location changes. The proposed scheme implemented on NS2 and performance evaluations are scrutinized to demonstrate the comparison of proposed simultaneous handover latency with LS and in absence of LS. The results show that our proposed approach has improved performance in reducing handover delay as well as handling simultaneous mobility issues in seamless handover.
