Mobility Support for Networks on Trains Using Commercial Off-the-shelf Routers

With the increasing demand for Internet access on the public transport, enabling network support on trains becomes an important topic. Trains can move at high speeds and for long distances, so their networks need to attach to different points of the Internet during mobility. In order to prevent user devices from experiencing any interruption of Internet access, it calls for network mobility (NEMO) support to handover the train's network from one access network to another. Though the network mobility protocols have been stipulated in IETF standards, only the default IPv6 NEMO is supported in commercial off-the-shelf(COTS) routers. It causes an issue to support mobility for mobile IPv4 wireless networks, which most networks and devices are using. Moreover, we discover that an intuitive solution, NAT-PT (Network Address Translator-Protocol Translator) for the IPv4/IPv6 conversion, is not applicable to addressing the issue. To this end, we propose a practical solution that uses COTS routers to support the IPv4 network mobility. On top of the IPv6 NEMO protocol, it leverages other three techniques: IPv4 tunneling, IPv4 over IPv6 tunnel, and network address translation (NAT). It allows user devices on a train to access the Internet via the train's mobile router, an access router on the ground, and the mobile router's home agent. Our prototype and evaluation results confirm the viability of the solution.
