Abstract
Device, system and method, in a vehicle communication system of wirelessly forwarding safety related messages. Methods are provided for limiting the number of duplicated transmissions. Methods are provided for limiting the scope of forwarded message. One embodiment uses the distance of the message originator to a first message forwarder to limit duplicate messages. Various embodiments limit the scope of messages forwarding by using a forwarding count; by considering distance forwarded, and by considering the heading of vehicles performing the message forwarding. Forwarding distance depends of message type and the risk contained within the message, in some embodiments. An embodiment uses a compact message encoding to identify an original versus a forwarded message.
