With the advent of new technologies in both hardware and software, we are in the need of a new type of application that requires huge computation power and minimal delay. Applications such as face recognition, augmented reality, virtual reality, automated vehicles, industrial IoT, etc. belong to this category. Cloud computing technology is one of the candidates to satisfy the computation requirement of resource-intensive applications running in UEs (User Equipment) as it has ample computational capacity, but the latency requirement for these applications cannot be satisfied by the cloud due to the propagation delay between UEs and the cloud. To solve the latency issues for the delay-sensitive applications a new network paradigm has emerged recently known as Multi-Access Edge Computing (MEC) (also known as mobile edge computing) in which computation can be done at the network edge of UE devices. To execute the resource-intensive tasks of UEs in the MEC servers hosted in the network edge, a UE device has to offload some of the tasks to MEC servers. Few survey papers talk about task offloading in MEC, but most of them do not have in-depth analysis and classification exclusive to MEC task offloading. In this paper, we are providing a comprehensive survey on the task offloading scheme for MEC proposed by many researchers. We will also discuss issues, challenges, and future research direction in the area of task offloading to MEC servers.

多接入边缘计算中的任务卸载调查

随着硬件和软件新技术的出现,我们需要一种需要强大计算能力和最小延迟的新型应用程序。人脸识别、增强现实、虚拟现实、自动驾驶汽车、工业物联网等应用都属于这一类。云计算技术是满足运行在 UE(用户设备)上的资源密集型应用的计算需求的候选技术之一,因为它具有充足的计算能力,但由于传播延迟,云无法满足这些应用的延迟需求UE和云之间。为了解决延迟敏感应用程序的延迟问题,最近出现了一种新的网络范例,称为多接入边缘计算 (MEC)(也称为移动边缘计算),其中计算可以在 UE 设备的网络边缘完成。为了在托管在网络边缘的 MEC 服务器中执行 UE 的资源密集型任务,UE 设备必须将一些任务卸载到 MEC 服务器。很少有调查论文谈到 MEC 中的任务卸载,但大多数都没有专门针对 MEC 任务卸载的深入分析和分类。在本文中,我们对许多研究人员提出的 MEC 任务卸载方案进行了全面调查。我们还将讨论任务卸载到 MEC 服务器领域的问题、挑战和未来的研究方向。为了在托管在网络边缘的 MEC 服务器中执行 UE 的资源密集型任务,UE 设备必须将一些任务卸载到 MEC 服务器。很少有调查论文谈到 MEC 中的任务卸载,但大多数都没有专门针对 MEC 任务卸载的深入分析和分类。在本文中,我们对许多研究人员提出的 MEC 任务卸载方案进行了全面调查。我们还将讨论任务卸载到 MEC 服务器领域的问题、挑战和未来的研究方向。为了在托管在网络边缘的 MEC 服务器中执行 UE 的资源密集型任务,UE 设备必须将一些任务卸载到 MEC 服务器。很少有调查论文谈到 MEC 中的任务卸载,但大多数都没有专门针对 MEC 任务卸载的深入分析和分类。在本文中,我们对许多研究人员提出的 MEC 任务卸载方案进行了全面调查。我们还将讨论任务卸载到 MEC 服务器领域的问题、挑战和未来的研究方向。在本文中,我们对许多研究人员提出的 MEC 任务卸载方案进行了全面调查。我们还将讨论任务卸载到 MEC 服务器领域的问题、挑战和未来的研究方向。在本文中,我们对许多研究人员提出的 MEC 任务卸载方案进行了全面调查。我们还将讨论任务卸载到 MEC 服务器领域的问题、挑战和未来的研究方向。
