摘要:

协作式智能交通系统依赖一系列车联网(V2X)应用来提升道路安全。新兴的V2X应用,如高级驾驶辅助系统(ADAS)和互联自动驾驶(CAD)应用,依赖于大量共享数据,并要求高可靠性、低端到端(E2E)时延和高吞吐量。然而,现有的V2X通信技术,如ITS-G5和C-V2X(蜂窝车联网),单独无法满足这些要求。本文提出了一种智能、可扩展的混合车载通信架构,利用多种无线接入技术(RAT)的性能来满足这些应用的需求。随后,我们提出了一种基于深度强化学习(DRL)的通信模式选择算法,以在限制资源消耗的同时最大化网络可靠性。最后,我们使用要求高可靠性的车辆编队行驶场景对所提方案进行了评估。数值结果表明,与静态RAT选择策略和多准则决策(MCDM)选择算法相比,混合车载通信架构有潜力将数据包接收率(PRR)提升最多30%。此外,在资源消耗方面,它将冗余通信模式的效率提高了20%。

英文摘要:

Cooperative intelligent transport systems rely on a set of Vehicle-to-Everything (V2X) applications to enhance road safety. Emerging new V2X applications like Advanced Driver Assistance Systems (ADASs) and Connected Autonomous Driving (CAD) applications depend on a significant amount of shared data and require high reliability, low end-to-end (E2E) latency, and high throughput. However, present V2X communication technologies such as ITS-G5 and C-V2X (Cellular V2X) cannot satisfy these requirements alone. In this paper, we propose an intelligent, scalable hybrid vehicular communication architecture that leverages the performance of multiple Radio Access Technologies (RATs) to meet the needs of these applications. Then, we propose a communication mode selection algorithm based on Deep Reinforcement Learning (DRL) to maximize the network's reliability while limiting resource consumption. Finally, we assess our work using the platooning scenario that requires high reliability. Numerical results reveal that the hybrid vehicular communication architecture has the potential to enhance the packet reception rate (PRR) by up to 30% compared to both the static RAT selection strategy and the multi-criteria decision-making (MCDM) selection algorithm. Additionally, it improves the efficiency of the redundant communication mode by 20% regarding resource consumption
