An Efficient Message Dissemination Technique in Platooning Applications

Abstract

Abstract-Autonomous driving in road trains, a.k.a. platooning, may reduce fuel consumption considerably if the intervehicle distances are kept short. However, to do this, the intraplatoon communication must not only be reliable but also able to meet strict deadlines. While time-triggered messages are the foundation of most distributed control applications, platooning is likely to also require dissemination of event-driven messages. While much research work has focused on minimizing the age of periodic messages, state-of-the-art for disseminating eventdriven messages is to let all nodes repeat all messages and focus on mitigating broadcast storms. We derive an efficient message dissemination scheme based on relay selection which minimizes the probability of error at the intended receiver(s) for both unicast and broadcast, without degrading the performance of co-existing time-triggered messages. We present a full analysis of the resulting error probability and delay, when relayers, selected by our algorithm, are used to disseminate messages within a platoon. Numerical results indicate that the proposed relaying policy significantly enhances the reliability for a given delay.

An Energy Efficient Message Dissemination Scheme in Platoon-Based Driving Systems

“…To the present, a lot of studies about information dissemination have been conducted on facilitating vehicular networks over the platooning-based driving in [7][8][9][10][11][12][13][14][15]. The studies mainly focuses on spectral efficiency, transmission reliability, and transmission delay of the vehicular networks.…”

“…The studies mainly focuses on spectral efficiency, transmission reliability, and transmission delay of the vehicular networks. For example, Hoang et al [15] proposed an event-driven message dissemination scheme that minimizes the probability of packet error at the intended receiver based on relay selection. Even though these works can improve the performance of the vehicular networks over the platoon, they do not fully consider the energy efficiency in terms of the maintenance of the platooning.…”
