Problems and tentative solutions in InternetCAR testing with IPv6

The vehicle environment is a good testbed to investigate Internet mobility technologies. Based on testing of buildings, protocol implementation details and problems to deploy it are clarified. This paper describes them. The InternetCAR Project had already done testing to connect vehicles to the IPv6 Internet. Some applications including vehicle diagnosis and teleconference, are implemented on the test system. The test system has the following functions: 1) several communication media with a media switching technology, 2) MobileIPv6 function for continuous connectivity, and 3) network mobility (NEMO) function to provide continuous Internet connectivity for an in-vehicle network. This paper introduces the problems of developing the InternetCAR testing system. The design and solutions are also described.
