摘要:

自动驾驶汽车、增强/虚拟现实设备和安全应用等低延迟物联网应用需要高计算资源才能在运行中做出决策。然而,由于经历的延迟,这些类型的应用程序不能容忍将其任务卸载到云基础设施上处理。因此,引入边缘计算是为了通过将任务处理移动到更靠近网络边缘的用户来实现低延迟。网络边缘的特征在于形成它的边缘设备的异质性;因此,设计考虑每个边缘设备的不同物理资源的新颖解决方案至关重要。在本文中,我们提出了一种资源表示方案,允许每个边缘设备暴露其资源信息的边缘节点的主管通过移动边缘计算应用程序编程接口提出的欧洲电信标准协会。每当需要资源分配时,关于边缘设备资源的信息被暴露给EN的监管者。为此,我们利用李亚普诺夫优化框架在边缘设备上动态分配资源。为了测试我们提出的模型,我们进行了密集的理论和实验模拟的测试平台上,以验证所提出的方案及其对不同系统的参数的影响。模拟表明,我们提出的方法优于其他基准方法,并提供低延迟和最佳资源消耗。

英文摘要:

Low-Latency IoT applications such as autonomous vehicles, augmented/virtual reality devices and security applications require high computation resources to make decisions on the fly. However, these kinds of applications cannot tolerate offloading their tasks to be processed on a cloud infrastructure due to the experienced latency. Therefore, edge computing is introduced to enable low latency by moving the tasks processing closer to the users at the edge of the network. The edge of the network is characterized by the heterogeneity of edge devices forming it; thus, it is crucial to devise novel solutions that take into account the different physical resources of each edge device. In this paper, we propose a resource representation scheme, allowing each edge device to expose its resource information to the supervisor of the edge node through the mobile edge computing application programming interfaces proposed by European Telecommunications Standards Institute. The information about the edge device resource is exposed to the supervisor of the EN each time a resource allocation is required. To this end, we leverage a Lyapunov optimization framework to dynamically allocate resources at the edge devices. To test our proposed model, we performed intensive theoretical and experimental simulations on a testbed to validate the proposed scheme and its impact on different system's parameters. The simulations have shown that our proposed approach outperforms other benchmark approaches and provides low latency and optimal resource consumption.
