AI 中文摘要
车载云计算（VCC）利用车辆中已嵌入的计算硬件，用于与任务卸载无关的目的，并将其空闲周期用于执行最终用户卸载的任务，从而避免部署新的计算基础设施。尽管其在概念上具有吸引力，但由于缺乏定量证据表明共享车辆空闲容量是可行、有利可图且可持续的，其采用受到阻碍。一种任务卸载管理方案通过将截止时间感知的分配与事后激励设计解耦，维持截止时间约束的执行，使该方法可行。一种稳健的联盟博弈和车辆选择机制即使在随机环境的不利结果下（例如，移动性、无线电条件或车辆夸大其空闲容量）也能保持网络运营商和车辆所有者的盈利能力。一项基于真实城市交通的模拟活动，使用罗马的SUMO（城市交通仿真）轨迹，并结合针对边缘计算基础设施的CO2生命周期评估（其足迹按用于卸载的容量比例分摊），表明该方法具有可持续性。车辆在几十毫秒内吸收了大部分卸载流量；参与每辆车每月可增加高达157公里的行驶里程；与边缘基础设施相比，使用VCC的生命周期排放量下降了超过99%。
英文摘要
Vehicular Cloud Computing (VCC) exploits computing hardware already embedded in vehicles for purposes unrelated to offloading and puts its idle cycles to work executing end-users' offloaded tasks, avoiding the deployment of new computation infrastructure. Despite its conceptual appeal, adoption is hindered by the lack of quantitative evidence that sharing spare vehicular capacity is viable, profitable and sustainable. A management scheme for task offloading sustains deadline-constrained execution by decoupling deadline-aware allocation from ex-post incentive design, making the approach viable. A robust coalitional game and a vehicle-selection mechanism keep the network operator and the vehicle owners profitable even under unfavorable outcomes of the random environment, e.g.,mobility, radio conditions, or vehicles overstating their spare capacity. A simulation campaign on realistic urban mobility, using Simulation of Urban MObility (SUMO) traces of Rome,together with a CO2 life-cycle assessment against edge computing infrastructure, whose footprint, is attributed pro rata to the share of its capacity devoted to offloading shows the approach to be sustainable. Vehicles absorb most of the offloaded traffic within tens of milliseconds; participation yields up to 157 km of monthly driving range per vehicle; and life-cycle emissions drop by over 99% when using VCC compared to that edge infrastructure.
