This paper proposes and measures the performance of an error control scheme for reliable message multicast on vehicular telematics networks, aiming at improving successful delivery ratio for the safety applications. Periodically triggered by an access point on the mobile gateway, the error recovery procedure collects the error reports from the reachable vehicles and decides the packet to retransmit considering available network bandwidth. The control scheme basically selects the message vehicles have missed most, giving additional precedence to messages belonging to a vehicle that is about to leave the gateway. The performance measurement result obtained via simulation using a discrete event scheduler shows that the proposed scheme can enhance the number of recovered messages by up to 12 % compared with the maximum selection scheme, showing better recovery ratio almost all ranges of given parameters.
