When Will the Automotive Internet Arrive?
DeviceGuru writes "European researchers are developing a cooperative traffic system, known CVIS (Cooperative Vehicle-Infrastructure Systems), comprised of vehicle-, roadside-, and central infrastructure-based communications hardware and software, including vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) wireless. Among other capabilities, cars communicate with each other and with 'smart traffic signals' to smooth the flow of traffic and avoid accidents, or with 'smart traffic signs' to avoid dangerous driving conditions. The CVIS project is in the midst of undergoing field trials in Europe, and Audi has recently deployed 15 test vehicles in a similar project. The ambitious vision of intelligent transportation systems (ITS) includes goals such as reduced traffic congestion and fuel consumption, enhanced safety, and improved driver and passenger comfort. Ultimately, the developers envision a sort of Automotive Internet."
They use IPV6 and linux.
In CVIS, the standard network protocol for 2G/3G communication is IPv6 (Internet Protocol version 6). In case no native IPv6 is available via 2G/3G, IPv6-over-IPv4 tunnelling can be accomplished via a CVIS-specific tunnel device driver and some sort of tunnelling software like OpenVPN.
The Operating System is the key foundation of the CVIS platform. The choice of operating system fundamentally affects portability, stability and extendibility of the whole CVIS system. Linux was chosen as it is freely available, has good quality, industry-standard development
tools and its license arrangements require access to source code.
