Method and apparatus for filtering and processing received vehicle peer transmissions based on reliability information

摘要

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.

主权项

1. A method for processing peer transmissions within a highway communication system, comprising:
determining a reliability of a message to be transmitted as a peer transmission within the highway communication system; including an indicator of the determined reliability in the message when it is transmitted; and assigning a priority to the message based at least in part on the determined reliability of the message, wherein the determined reliability includes an inaccuracy of measurement or identification of a method used to estimate a value reported in the message.
