Network Load of push and pull delivery for driver assistance systems

摘要

Car-to-Car communication is used to improve road traffic safety through active measures. Vehicle occupant safety can be improved by passive and active safety elements. In contrast to passive safety elements, which protect the driver in case of an accident, active elements warns the driver of imminent danger with the aim to prevent or minimize the severity of accidents. Sensor data regarding traffic and unexpected events are evaluated and exchanged between vehicles. A central unit should reach vehicles, which depend on the position, via cellular infrastructure and forward data e.g. warnings about event-controlled data in form of push-messages. Thereby, existing push-services have to be analyzed. The resulting network load is compared with the standard pull-service.
