摘要:

随着物联网(IoT)的普及和无线网络的广泛渗透,对数据通信和计算的需求激增,需要新兴的边缘计算模式。通过将位于云中的服务和功能移动到用户附近,边缘计算可以提供强大的通信,存储,网络和通信能力。边缘计算中的资源调度是边缘计算系统成功的关键,引起了越来越多的研究兴趣。本文通过对国内外相关研究成果的综述,了解该领域的研究进展。具体来说,我们提出了边缘计算的体系结构,在此基础上讨论了不同的协作方式的资源调度。特别是,我们介绍了一个统一的模型,然后总结了目前的工作,资源调度的三个研究问题,包括计算卸载,资源分配,资源供应。基于两种操作模式,即,集中式和分布式两种模式,讨论和比较了不同的资源调度技术。此外,我们总结了主要的性能指标的基础上调查的文献。为了阐明资源调度在现实场景中的重要性,我们讨论了边缘计算中资源调度研究所涉及的几个典型应用场景。最后,我们强调了一些开放的研究挑战尚未解决,并概述了几个开放的问题,作为未来的研究方向。

英文摘要:

With the proliferation of the Internet of Things (IoT) and the wide penetration of wireless networks, the surging demand for data communications and computing calls for the emerging edge computing paradigm. By moving the services and functions located in the cloud to the proximity of users, edge computing can provide powerful communication, storage, networking, and communication capacity. The resource scheduling in edge computing, which is the key to the success of edge computing systems, has attracted increasing research interests. In this paper, we survey the state-of-the-art research findings to know the research progress in this field. Specifically, we present the architecture of edge computing, under which different collaborative manners for resource scheduling are discussed. Particularly, we introduce a unified model before summarizing the current works on resource scheduling from three research issues, including computation offloading, resource allocation, and resource provisioning. Based on two modes of operation, i.e., centralized and distributed modes, different techniques for resource scheduling are discussed and compared. Also, we summarize the main performance indicators based on the surveyed literature. To shed light on the significance of resource scheduling in real-world scenarios, we discuss several typical application scenarios involved in the research of resource scheduling in edge computing. Finally, we highlight some open research challenges yet to be addressed and outline several open issues as the future research direction.
