Method and apparatus for filtering and processing received vehicle peer transmissions based on reliability information
Methods and devices for processing and retransmitting highway communication system transmissions include determining a reliability of a received message and including an indication of the reliability in retransmitted transmissions. Reliability of received messages may be based on a signal strength of the received peer transmission, comparison of the signal strength to a distance to the transmitter based on message contents, the age of the received message, the signal quality of the received message, and other parameters. An indication of the determined reliability may be included in retransmissions of the message to enable other vehicles and receiver units in the highway communication system to benefit from the reliability determination. Message reliability may be used as part of prioritizing messages for processing. Messages may be processed according to priority so that high priority messages are processed before lower priority messages.
