Abstract: A method for supplying data which can be received by a vehicle in a vehicular ad-hoc network, in which the data is transmitted between subscribers to the vehicular ad-hoc network using a location-based communications protocol, involves: identifying a geographical location area of the vehicle; selecting a suitable communications protocol (for the identified location area; and receiving the data using the selected communications protocol in such a way that the received data is available to at least one network layer of the communications protocol.

Abstract: The disclosure relates to a method for generating a time stamp in a vehicle which participates in a vehicle ad-hoc network. The method includes associating, by giving out the time stamp, an event, which is transmitted in a message, with a clock time. The clock time is generated by updating a global time base that may be derived from a global satellite navigation signal (GNSS). The method includes checking whether a GNSS signal may be received. The method also includes generating the clock time based on a local time base if an insufficient number of global satellite navigation signals for deriving the global time base is available.

Abstract: An electronic control device comprising a number of application partitions and a firewall partition, also comprising a number of secure interfaces which can only be accessed by the firewall partition. This increases the safety of the electronic device for example when used as an embedded controller.
