摘要:

随着物联网技术的进步,智能工厂、智能城市和智能汽车等各个领域都在使用物联网提供增值服务。此外,MEC和网络切片等技术为物联网提供了另一个机会,可以支持以前无法支持的更先进和实时的服务。然而,将这些技术简单地集成到物联网中并没有充分利用MEC和网络切片,或者分别减少延迟和流量优先级。因此,迫切需要一种有效的物联网平台集成机制,以最大限度地发挥使用此类技术的优势。在本文中,我们介绍了一种新颖的架构框架,该框架能够以最少的功能虚拟化物联网平台,以支持特定的物联网服务,并在靠近最终用户的边缘节点上托管实例。由于实例在MEC节点和网络切片所在的边缘节点处提供其服务,因此最终用户的流量不需要遍历回到云。这种架构不仅保证了低延迟,还保证了边缘节点处物联网服务的有效管理。为了证明所提出的架构的可行性,我们通过比较在中央云上运行的物联网服务和在边缘网关中使用切片物联网功能的物联网服务的传输时间来进行实验评估。结果表明,所提出的架构提供的传输时间比传统的基于云的物联网平台快两倍。

英文摘要:

With the advancement of IoT technology, various domains such as smart factories, smart cities and smart cars use the IoT to provide value-added services. In addition, technologies such as MEC and network slicing provide another opportunity for the IoT to support more advanced and real-time services that could not have been previously supported. However, the simple integration of such technologies into the IoT does not take full advantage of MEC and network slicing or the reduction of latency and traffic prioritization, respectively. Therefore, there is a strong need for an efficient integration mechanism for IoT platforms to maximize the benefit of using such technologies. In this article, we introduce a novel architectural framework that enables the virtualization of an IoT platform with minimum functions to support specific IoT services and host the instance in an edge node, close to the end-user. As the instance provides its service at the edge node where the MEC node and network slice are located, the traffic for the end-user does not need to traverse back to the cloud. This architecture guarantees not only low latency but also efficient management of IoT services at the edge node. To show the feasibility of the proposed architecture, we conduct an experimental evaluation by comparing the transmission time of both IoT services running on the central cloud and those using sliced IoT functions in the edge gateway. The results show that the proposed architecture provides two times faster transmission time than that from the conventional cloud-based IoT platform.
