Mobile networks can be formed in bus, train, aircrafts, satellites with a wide variety of on-board IP-enabled devices and NEtwork MObility (NEMO) protocols are required to support uninterrupted services to ongoing sessions. Earlier works have not demonstrated seamless handover for NEMO architecture. In this paper, the authors proposed a handover scheme for NEMO that exploits the multi-homing feature of the Mobile Router and uses make-before-break strategy to ensure seamless handover for NEMO. Using experimental testbed, they have presented a thorough handoff performance evaluation of multihomed NEMO and compared it with basic NEMO. Results demonstrate that the proposed multihomed NEMO outperforms the basic NEMO while achieving seamless handover.
