一种软件定义工业物联网系统架构

A System Architecture for Software-Defined Industrial Internet of Things

Peng Hu

摘要:

无线传感器网络一直是过程控制和制造业中工业物联网(IIoT)发展的驱动力。IIoT的出现为无处不在的现场设备连接和可扩展性提供了巨大的潜力,从低级设备操作到以数据为中心的高级应用交互都具有集成和标准化的架构。这种技术发展要求IIoT的关键架构元素具有软件可定义性,包括无线现场设备、IIoT网关、网络基础设施和IIoT传感器云服务。本文提出了一种新的软件定义IIoT(SD-IIoT),以解决整体IIoT系统中的关键挑战,例如可靠性,安全性,及时性可扩展性和服务质量(QoS)。基于WirelessHART、WebSocket、IETF约束应用协议(CoAP)和软件定义网络(SDN)等最新网络技术,提出了一种新的工业物联网系统架构。提出了一种基于CoAP和SDN的QoS解决方案。计算机实验的案例研究,以显示所提出的系统架构的有效性。

英文摘要:

Wireless sensor networks have been a driving force of the Industrial Internet of Things (IIoT) advancement in the process control and manufacturing industry. The emergence of IIoT opens great potential for the ubiquitous field device connectivity and manageability with an integrated and standardized architecture from low-level device operations to high-level data-centric application interactions. This technological development requires software definability in the key architectural elements of IIoT, including wireless field devices, IIoT gateways, network infrastructure, and IIoT sensor cloud services. In this paper, a novel software-defined IIoT (SD-IIoT) is proposed in order to solve essential challenges in a holistic IIoT system, such as reliability, security, timeliness scalability, and quality of service (QoS). A new IIoT system architecture is proposed based on the latest networking technologies such as WirelessHART, WebSocket, IETF constrained application protocol (CoAP) and software-defined networking (SDN). A new scheme based on CoAP and SDN is proposed to solve the QoS issues. Computer experiments in a case study are implemented to show the effectiveness of the proposed system architecture.
