摘要

目前的任务卸载技术需要更有效地执行。由于数据流的爆炸式扩张、车辆数量的快速增长以及频谱资源的日益稀缺,车载终端无法执行高效计算。因此,本研究为车联网边缘计算架构提出了一种基于强化学习计算的任务卸载技术。车联网的系统框架已初步建立。虽然控制中心会收集所有车辆信息,但路边装置会收集附近的车辆数据并发送到移动边缘计算服务器进行处理。然后,为了保证车辆互联网中的工作调度符合逻辑,建立了计算模型、通信方法、干扰方法以及对保密性的关注。本研究探讨了分析和设计基于移动边缘计算(MEC)的多用户智能车联网(IoV)计算卸载方法的最佳途径。我们针对各种 MEC 网络提出了一种分析性卸载策略,涵盖一对一、一对二和二对一的情况,因为确定基于 MEC 的通用 IoV 网络的分析性卸载比例具有挑战性。建议的分析卸载策略可与蛮力(BF)方法和深度确定性策略梯度(DDPG)的最佳性能相匹配。对于一般基于 MEC 的 IoV 的分析卸载设计,本研究的分析结果可以作为宝贵的信息来源。

Development of Analytical Offloading for Innovative Internet of Vehicles Based on Mobile Edge Computing

The current task offloading technique needs to be performed more effectively. Onboard terminals cannot execute efficient computation due to the explosive expansion of data flow, the quick increase in vehicle population, and the growing scarcity of spectrum resources. As a result, this study suggests a task-offloading technique based on reinforcement learning computing for the Internet of Vehicles edge computing architecture. The system framework for the Internet of Vehicles has been initially developed. Although the control centre gathers all vehicle information, the roadside unit collects vehicle data from the neighborhood and sends it to a mobile edge computing server for processing. Then, to guarantee that job dispatching in the Internet of Vehicles is logical, the computation model, communications approach, interfering approach, and concerns about confidentiality are established. This research examines the best way to analyze and design a computation offloading approach for a multiuser smart Internet of Vehicles (IoV) based on mobile edge computing (MEC). We present an analytical offloading strategy for various MEC networks, covering one-to-one, one-to-two, and two-to-one situations, as it is challenging to determine an analytical offloading proportion for a generic MEC-based IoV network. The suggested analytic offload strategy may match the brute force (BF) approach with the best performance of the Deep Deterministic Policy Gradient (DDPG). For the analytical offloading design for a general MEC-based IoV, the analytical results in this study can be a valuable source of information.
