Abstract
Apparatus for V2X communications comprising an application layer configured to analyze a high-risk scenario involving a self-vehicle and other vehicles, an access or network layer configured to ensure reception of messages broadcast by the self-vehicle by requesting acknowledged only from vehicles identified as involved in the high-risk scenario, and an interface connecting the application layer to the access or network layer for carrying results of the analysis of the high-risk scenario and the identification of involved vehicles. In an exemplary method of use, a self-vehicle performing identifies vehicles involved in a high-risk scenario, broadcasts one or more times a first message that can prevent or mitigate the high-risk, requests acknowledgement for the first message from only the identified vehicles, and rebroadcasts the first message if acknowledgement is not received from all the identified vehicles before a predetermined condition is fulfilled.
