The Car2Car Communication Consortium is a non-profit organisation initiated by European vehicle manufacturers, which is open for suppliers, research organisations and other partners. The Consortium is dedicated to the objective of further increasing road traffic safety and efficiency by means of inter-vehicle communication. The mission and the objectives of the Consortium are to create and establish an open European industry standard for Car2Car communication based on W-LAN components and to guarantee European-wide inter-vehicle operability, to enable the development of active safety applications by specifying, prototyping and demonstrating the Car2Car system, to promote the allocation of a royalty free European wide exclusive frequency band for Car2Car applications, to push the harmonisation of Car2Car Communication standards worldwide and to develop realistic deployment strategies and business models to speed-up the market penetration. The applications will mainly evolve three areas: advanced driver assistance (increasing road safety by reducing the number of accidents as well as reducing the impact in case of non-avoidable accidents), decentralised floating car data (improving local traffic flow and efficiency of road traffic) and user communications and information services (offering comfort and business applications to driver and passengers). The radio system for Car2Car Communication is derived from W-LAN. As soon as two or more vehicles are in radio communication range, they connect and establish an ad hoc network. As the range of a single Wireless LAN link is limited to a few hundred meters, every vehicle is also a router and allows sending messages over multi-hop to farther vehicles. The routing algorithm is based on the position of the vehicles and is able to handle fast changes of the ad hoc network topology. The W-LAN link would also allow infrastructure connections, e.g. to hotspots, traffic lights or road signs.
