Abstract

With the rapid development of the Internet of Vehicles (IoV), vehicles will generate massive data and computation demands, necessitating computation offloading at the edge. However, existing research faces challenges in efficiency and trust. In this paper, we explore the IoV computation offloading from both user and edge facility provider perspectives, working to optimize the quality of experience (QoE), load balancing, and success rate based on challenges to efficiency and trust. First, two vehicle interconnection models are constructed to extend the linkable range of intra-road and inter-road vehicles while considering the maximum link time constraint. Then, a dynamic planning method is proposed, combining the reputation and feedback mechanisms, which can schedule edge resources online based on the cumulative computation latency of each service side, reliability value, and historical behavior. These two phases further improve the efficiency of edge services. Subsequently, blockchain is combined to optimize the trust problem of edge collaboration, and an edge-limited Byzantine fault tolerance local consensus mechanism is proposed to optimize consensus efficiency and ensure the reliability of edge services. Finally, this paper conducts dynamic experiments on real-world datasets, verifying the effectiveness of the proposed algorithm and models in multiple vehicle density datasets and experimental scenarios.
车联网计算卸载模型与策略优化:效率与信任
随着车联网(IoV)的快速发展,车辆将产生大量的数据和计算需求,需要在边缘卸载计算。然而,现有的研究面临着效率和信任方面的挑战。在本文中,我们从用户和边缘设施提供商的角度探讨了车联网计算卸载,致力于优化体验质量(QoE)、负载平衡和基于效率和信任挑战的成功率。首先,在考虑最大连接时间约束的情况下,构建了两种车辆互联模型,以扩大道路内和道路间车辆的可连接范围;然后,提出了一种结合信誉机制和反馈机制的动态规划方法,该方法可以根据各服务端的累积计算延迟、可靠性值和历史行为在线调度边缘资源。这两个阶段进一步提高了边缘服务的效率。随后,结合区块链优化边缘协作的信任问题,提出一种边缘受限的拜占庭容错局部共识机制,优化共识效率,保证边缘业务的可靠性。最后,本文在真实数据集上进行了动态实验,在多个车辆密度数据集和实验场景下验证了算法和模型的有效性。
