IP Mobility Support with a Multihomed Mobile Router

This paper proposes a multihoming-based seamless handover scheme using a mobile router with dual egress interfaces for wireless train networks. The proposed scheme deploys dual antennas which are individually located at each end of the train for space diversity and connected to each egress interface of a mobile router. Since one of the two egress interfaces of the mobile router can continuously receive packets through its antenna while the other is undergoing a handover, the proposed scheme can support a seamless handover providing no service disruption or packet loss.
