Strategies for monitoring CAN node communication failures in the V2X eco-system

Numerous technologies have been deployed to manage and assist transportation. Vehicular Communication using Dedicated Short Range Communication is one such technology being used as a part of Advanced Driver Assistant System. V2X Communication involves broadcast of vehicle information such as vehicle speed and position to surrounding vehicles and to the Road Side unit. Reliable communication between the nodes of a vehicular network must happen, when it comes to the transfer of critical data messages. This work studies the sliding window and alive rolling count approaches for exchange of Controller Area Network (CAN) messages in the V2X ecosystem. The performance of these methods in monitoring communication failures and maintaining system stability is illustrated.
