Event Based

Most industrial and SCADA-like (supervisory control and data acquisition) systems use proprietary communication protocols, and hence interoperability is not fulfilled. However, the MODBUS TCP is an open de facto standard, and is used for some automation and telecontrol systems. It is based on a polling mechanism and follows the synchronous request–response pattern, as opposed to the asynchronous publish–subscribe pattern. In this study, polling-based and event-based protocols are investigated to realize an open and interoperable Industrial Internet of Things (IIoT) environment. Many Internet of Things (IoT) protocols are introduced and compared, and the message queuing telemetry transport (MQTT) is chosen as the event-based, publish–subscribe protocol. The study shows that MODBUS defines an optimized message structure in the application layer, which is dedicated to industrial applications. In addition, it shows that an event-oriented IoT protocol complements the MODBUS TCP but cannot replace it. Therefore, two scenarios are proposed to build the IIoT environment. The first scenario is to consider the MODBUS TCP as an IoT protocol, and build the environment using the MODBUS TCP on a standalone basis. The second scenario is to use MQTT in conjunction with the MODBUS TCP. The first scenario is efficient and complies with most industrial applications where the request–response pattern is needed only. If the publish–subscribe pattern is needed, the MQTT in the second scenario complements the MODBUS TCP and eliminates the need for a gateway; however, MQTT lacks interoperability. To maintain a homogeneous message structure for the entire environment, industrial data are organized using the structure of MODBUS messages, formatted in the UTF-8, and then transferred in the payload of an MQTT publish message. The open and interoperable environment can be used for Internet SCADA, Internet-based monitoring, and industrial control systems.

Secure Network

Digital transformation, or Industry 4.0, is already changing manufacturing processes as it brings more automation to standardized Industrial Control Systems (ICS) based systems such as Supervisory Control and Data Acquisition (SCADA) systems. It is performed by the means of cyber-physical systems such as Internet of Things (IoT). For now, these “Things” are communicating in a new network area, where peer-to-peer communications are widely used. Such networks are responsible for real life processes safety. However, such shift also extends a threat vectors and entry points for an adversary inside the industrial segments. In the paper, new cybersecurity challenges on the Industrial Internet of Things network segments are considered as well as known practices to mitigate some of them. As a result, a peer-to-peer smart multipath network routing based on garlic routing is proposed to model secure network communications in IoT field. An approach is aimed to be used on the IoT field to tackle all of the network-scoped cybersecurity challenges.

Diagnosis Model

With the rapid development of intelligent manufacturing and Industrial Internet of Things, many industrial control systems have high requirements for the security of the system itself. Failures of industrial control equipment will cause abnormal operation of industrial control equipment and waste of resources. It is very meaningful to detect and identify potential equipment abnormalities and failures in time and implement effective fault tolerance strategies. In the Industrial Internet of Things environment, the instructions and parameters of industrial control equipment often change due to changes in actual requirements. However, it is impractical to customize the learning method for each parameter value. Aiming at the problem, this paper proposes a fault diagnosis model based on ensemble learning and proposes a method of updating voting weights based on dynamic programming to assist decision-making. This method is based on Bagging strategy and combined with dynamic programming voting weight adjustment method to complete fault type prediction. Finally, this paper uses different loads as dynamic conditions; the diagnostic capability of the Bagging-based fault diagnosis integrated model in a dynamically changing industrial control system environment is verified by experiments. The fault diagnosis model of industrial control equipment based on ensemble learning effectively improves the adaptive ability of the model and makes the fault diagnosis framework truly intelligent. The voting weight adjustment method based on dynamic programming further improves the reliability of voting.

Through the Industrial Internet of Things (IIoT), a smart factory has entered the boom period expecting significant investments. In this new environment, Machine-to-Machine (M2M) communication has shown immediate potential in IIoT applications. However, most M2M communication implementations use the centralized model in which it requires a reliable intermediary for transactions between machines. Using smart contracts in M2M communication would allow a decentralized network to be used without the need for a trusted intermediary. In order to provide security, privacy, and decentralization in M2M communication and IIoT processes, a middleware based on a smart contract is proposed. Such a proposal is analyzed at the industrial level and evaluated for impacts against the stringent communication requirements that industrial applications require. Experimental results show that the application of smart contracts offers greater security and privacy than traditional proposals, but time requirements of real-time systems must still be optimized for smart contracts to be applied at the industrial field.

Internet of Things (IoT) with edge computation enhances efficiency, safety, and availability of an industrial automation system. However, there is a continued effort to increase the reliability of the system with minimal downtime. This can be achieved through a modular, re-configurable, and integrable system design approach. In this paper, we propose Pro-Edge, a programmable edge network to reconfigure different services associated with industrial applications and networks. Pro-Edge employs programmable layers at the edge for re-configuring the sensor/actuator network and applications. The lowermost layer allows to reconfigure the communication related parameters and the middle layer consists of a Software-Defined Network (SDN) controller that can dynamically program different modules, handling actuation decisions from the edge. An interfacing protocol between the layers is proposed to provide reliability by considering the optimal configuration parameters among the layers. As a top-layer, a priority forwarding mechanism is designed for SDN core communication in case the sensor and actuator are in different edges. Pro-Edge significantly improves the actuation-latency and is highly energy efficient compared to the existing state-of-the-art.
