Time Critical

Since the 1990s, the digitalization process has transformed the communication infrastructure within the electrical grid: proprietary infrastructures and protocols have been replaced by the IEC 61850 approach, which realizes interoperability among vendors. Furthermore, the latest networking solutions merge operational technologies (OTs) and informational technology (IT) traffics in the same media, such as time-sensitive networking (TSN)—standard, interoperable, deterministic, and Ethernet-based. It merges OT and IT worlds by defining three basic traffic types: scheduled, best-effort, and reserved traffic. However, TSN demands security against potential new cyberattacks, primarily, to protect real-time critical messages. Consequently, security in the smart grid has turned into a hot topic under regulation, standardization, and business. This survey collects vulnerabilities of the communication in the smart grid and reveals security mechanisms introduced by international electrotechnical commission (IEC) 62351-6 and how to apply them to time-sensitive networking.

The Social

Internet of Things (IoT) have become a hot topic since the official introduction of IPv6. Research on Wireless Sensors Networks (WSN) move towards IoT as the communication platform and support provided by the TCP/UDP/IP stack provides a wide variety of services. The communication protocols need to be designed in such a way that even simple microcontrollers with small amount of memory and processing speed can be interconnected in a network. For this different protocols have been proposed. The most extended ones, MQTT and CoAP, represent two different paradigms. In this paper, we present a CoAP extension to support soft real-time communications among sensors, actuators and users. The extension facilitates the instrumentation of applications oriented to improve the quality of life of vulnerable communities contributing to the social good.

IEC 61850-9-2 proposes the process bus communication for protection and automation within substations. The actual performance of process bus such as real-time, security and reliability are of concern, when transmission of sample values and trip signals over the same network. This paper presents the establishment of a dynamic simulation test platform, in order to facilitate the test of protection schemes over the process bus. An example is given to demonstrate that incorrect switch configuration, message priority tagging, and the volumes of traffic on the network may have an impact on the real time and reliability of the signals to be delivered.

The design of software system for unmanned surface vehicle using PCI8602 is introduced. The software system includes the drive program of PCI8602, wireless transmission program and master controller program. Visual Basic is used to write programs, which doesn’t write complicated communication protocols between each layers and integrating subsystem is easy. At last, the experiment results demonstrate that the control system for USV has a way to real-time acquisition data, sending data and accomplishing remote control.
