METHOD FOR BUILDING AN AD HOC VIRTUAL NETWORK AND SYSTEM

A method for setting up a virtual ad hoc network for transmitting at least one piece of information to a first transportation vehicle as a first network subscriber. The method includes the information being provided based on first data from at least one second network subscriber, and at least one second network subscriber being a second transportation vehicle or an infrastructure component; wherein a motor-vehicle-external, central data processing device receives second data from multiple potential second network subscribers and takes the second data and at least one space-time parameter as a basis for determining the second network subscribers and setting up the virtual ad hoc network with the first transportation vehicle, as the first network subscriber, and the determined second network subscribers, the space-time parameter defining a specific area of relevance that has a predetermined physical and temporal correlation with the current position of the first transportation vehicle.
