Wireless Traffic Service Communication Platform for Cars

Wireless communication between vehicles has been widely studied recently and a large number of suggestions for vehicle-to-vehicle communication have been presented. The main focus in these proposals has been on bilateral communication between two vehicles or on broadcasting information from one vehicle or infrastructure to vehicles in the surrounding area. The approach in the Carlink project of the Celtic program call 3 is to develop an intelligent hybrid wireless traffic service platform between cars supported with wireless tranceivers acting as access points beside the road(s). Communication between cars will be arranged in an ad-hoc manner, supported with wireless base station connection to the backbone network, whenever possible. The primary application is real-time local weather information, but also numerous other applications, such as accident warnings and traffic intensity information for route planning can be integrated to this kind of a system. In this paper we present the concept and use cases of the Carlink platform. The platform operability and efficiency analysis are topics of future publications.
