移动的云计算是一种新兴技术，用于促进智能手机上复杂应用程序的执行。云服务不仅用于加速移动的应用程序的运行，还用于为智能手机节省能源。在本文中，我们建议将联合收割机的车辆云与基础设施为基础的云，以扩大目前可用的资源，从智能手机的任务请求。在我们提出的架构中，车辆云充当智能手机的云服务提供商。此外，我们提出了一个灵活的卸载策略（FOS）进行任务迁移。车载云能够发现和利用车辆中未充分利用的资源，以实现智能手机的应用卸载。FOS根据当前的资源条件估计各种云服务提供商的效率，然后选择合适的云服务提供商来执行所请求的任务。实验结果表明，该方法可以提高智能手机上的移动的应用程序的性能方面的任务响应时间和能量消耗。
Mobile cloud computing is an emerging technology for facilitating complex application execution on smartphones. Cloud services are utilized not only to speed up the running of mobile applications but to save energy for smartphones as well. In this paper, we propose to combine the vehicular cloud with the infrastructure-based cloud to expand the current available resources for task requests from smartphones. In our proposed architecture, the vehicular cloud acts as a cloud service provider for smartphones. Moreover, we propose a flexible offloading strategy (FOS) to carry out task migration. The vehicular cloud is able to discover and utilize the underutilized resources in vehicles to accomplish application offloading for smartphones. The FOS estimates the efficiency of various cloud service providers based on current resource conditions and then selects the suitable cloud service provider to perform the requested task. Experimental results show that the proposed approach can improve the performance of mobile applications on smartphones in terms of task response time and energy consumption.
