Summary:A method for improving the reliability and performance of Vehicle-to-Vehicle (V2V) networks where digital certificates are necessary for message authentication and some messages may be lost in transmission. The method uses Forward Error Correcting (FEC) codes to encode a digital certificate into multiple segments, and attaches one or more segment to each message transmitted. Nodes receiving the messages can reconstruct the certificate as long as they successfully receive a minimum number of the transmitted messages, where the minimum number is less than the total number of messages transmitted. This allows message authentication to continue uninterrupted, even in a network environment where some messages are lost in transmission. Two different types of FEC codes are described, and adaptive schemes are included to optimize message throughput based on such network conditions as node density.
