近年来,尽管信息科技发展迅速,但一些巨大挑战仍阻碍着车联网的发展。一方面,车辆终端因其有限的资源,包括计算资源、存储资源和带宽资源,导致低效的数据处理能力,难以支持车载多媒体应用、车载社交网络和基于位置的服务。另一方面,智能交通系统包含海量数据,数据采集和分析实时性高,需要云计算的支持。本文将车联网、云计算和移动云计算的最新发展结合,提出基于VM迁移的车联网移动云系统网络设计,重点研究了中心云、路侧云、车载终端的三级网络架构,以及VM迁移模式,最后探讨了车联网移动云环境下的典型服务。
In recent years, despite the rapid development of information technology, some major challenges still hinder the development of car networking. On the one hand, vehicle terminals, due to their limited resources, including computing resources, storage resources and bandwidth resources, result in inefficient data processing capabilities that make it difficult to support automotive multimedia applications, automotive social networks and location-based services. On the other hand, the intelligent transportation system contains a large amount of data, which has high real-time data collection and analysis and needs cloud computing support. In this paper, we combine the latest development of car networking, cloud computing and mobile cloud computing to propose a VM network-based mobile network-based mobile cloud system design, focusing on the three-tier network architecture of the center cloud, roadside cloud, vehicle terminal and VM migration Model, and finally discusses the typical service in the car networking mobile cloud environment.
