Abstract

The integration of Internet of Things (IoT) technologies into the vehicular industry has initiated a new era of connected and autonomous vehicles, revolutionizing transportation systems. However, this transformation introduces significant challenges, especially in 5 G networks, such as achieving Ultra-Reliable Low-Latency Communications (URLLC) and maintaining energy efficiency within the high mobility of vehicular environments. These are essential for supporting sustainable and environmentally friendly computing practices. To address these challenges, this paper introduces a URLLC-aware and energy-efficient data offloading strategy, utilizing the Asynchronous Advantage Actor-Critic (A3C) algorithm to navigate the complex dynamics of vehicular Mobile Edge Computing (MEC) environments. Our proposed method balances latency and energy consumption trade-offs while ensuring robust communication reliability. Technical evaluations reveal that our approach significantly outperforms other algorithms, achieving up to 8.2 % energy savings and a reduction of over 29 % in latency.

高移动性车载移动边缘计算环境中的 URLLC 感知和高能效数据卸载策略

物联网（IoT）技术与车辆行业的融合开启了互联和自动驾驶车辆的新时代，彻底改变了交通系统。然而，这种变革带来了巨大的挑战，尤其是在 5 G 网络中，例如实现超可靠低延迟通信（URLLC）以及在车辆环境的高流动性中保持能源效率。这些对于支持可持续和环保的计算实践至关重要。为了应对这些挑战，本文介绍了一种具有 URLLC 感知和能效的数据卸载策略，利用异步优势行动者批判（A3C）算法来驾驭车载移动边缘计算（MEC）环境的复杂动态。我们提出的方法既能平衡延迟和能耗之间的权衡，又能确保稳健的通信可靠性。技术评估显示，我们的方法明显优于其他算法，实现了高达 8.2% 的能耗节省和超过 29% 的延迟减少。

期刊介绍： Vehicular communications is a growing area of communications between vehicles and including roadside communication infrastructure. Advances in wireless communications are making possible sharing of information through real time communications between vehicles and infrastructure. This has led to applications to increase safety of vehicles and communication between passengers and the Internet. Standardization efforts on vehicular communication are also underway to make vehicular transportation safer, greener and easier. The aim of the journal is to publish high quality peer–reviewed papers in the area of vehicular communications. The scope encompasses all types of communications involving vehicles, including vehicle–to–vehicle and vehicle–to–infrastructure. The scope includes (but not limited to) the following topics related to vehicular communications: Vehicle to vehicle and vehicle to infrastructure communications Channel modelling, modulating and coding Congestion Control and scalability issues Protocol design, testing and verification Routing in vehicular networks Security issues and countermeasures Deployment and field testing Reducing energy consumption and enhancing safety of vehicles Wireless in–car networks Data collection and dissemination methods Mobility and handover issues Safety and driver assistance applications UAV Underwater communications Autonomous cooperative driving Social networks Internet of vehicles Standardization of protocols.
