Abstract
In this paper we present a novel message forwarding algorithm, the reachability matrix algorithm, for V2V communication in a platooning scenario. The algorithm uses a communication quality estimate to determine appropriate forwarding candidates. We show that the algorithm achieve a higher reliability in the communication compared to only using broadcast but still keeping the message intensity at a low level. The reachability matrix algorithm can decrease the ratio of missing a data age limit of 0.2 seconds from 18% to 11%, a decrease of 40%, while increasing the message intensity by only 21% compared to only using broadcast. The evaluation has been performed through simulation using input from real-life V2V measurements on heavy duty trucks in a platooning scenario.
