Wide-Band Synchronous Automated Systems of Data Communication (ASDC)
Opis:
The architecture of wide-band synchronous automated systems of data communication (ASDC) enables utilization of high accuracy measurement of the signal reception times to relative navigation in the network. In this contribution an operation analysis of such systems in the relative navigation mode is conducted. The accuracy and possibilities of the utilization of these systems were examined by modeling in air navigation.

Opis:
Data communication is an important part in modern industrial processes and is necessary in automation, monitoring, and protection purposes. This paper aims at designing a real time communication between two computers for interchanging the state of a three phase circuit to emulate a transmission line protection system in power substation. The circuit designed in Proteus ISIS is based on "symmetrical component theory" and the algorithm for exchanging data between two computers is built using TCP/IP protocol in LABVIEW environment. The application consists of monitoring and controlling three phase lines by sending the data collected to one of the computers and sending the commands back to trip relays if any fault is detected. The purpose is to prevent the propagation of this fault and to connect other sources to maintain the flow of power to the load.

Opis:
The article deals with the application of the queuing theory apparatus for analysing the diagnostic processes of data transmission networks (DTN). It is shown that with an increase in the complexity of DTN and existing tools and algorithms for their diagnostics, it seems expedient to create automated diagnostics systems that take into account the disadvantages and advantages of existing network diagnostics methods. The existing analytical methods (in the capacity of which probabilistic methods of the queuing theory are used) and statistical (methods of simulation modelling) are presented. In terms of the queuing system, the analysis of the closed, open (QS) is carried out and their characteristics are determined. The analysis of the statistical method for modelling the diagnostic system in the GPSS World environment is carried out. Models of the DTN diagnostics system are considered from the point of view of closed and open queuing systems. For analytical models of DTN diagnostic systems, the possibility of using the QS is considered, as a result of which the general structure of the main elements and procedures for the functioning of the diagnostic system are determined. The analysis of the possibilities of using the queuing theory made it possible to determine the analytical regularities for the model of diagnostic systems. The creation of automated diagnostic systems based on a queuing system provides a deep and accurate analysis of the characteristics of diagnostics and, therefore, is a promising direction in the development of systems for the technical operation and maintenance of DTN.

Data communication security assurance in the Central Node of Poland's Schengen Information System and Visa Information System Component (in polish: Centralny Węzeł Polskiego Komponentu Systemu Informacyjnego Schengen i Systemu Informacji Wizowej - CW PK SIS i VIS) is crucial for building adequate trust of the operation of mechanisms of the Schengen agreement in Poland. Presented in this chapter are the security requirements, agreed by member states of the Schengen agreement, which fulfillment is subject to independent review during periodical SIS/SIRENE evaluations. The essence of law, organizational and technical role means have also been indicated for assuring a high level of SIS and VIS data communication security, which is higher than the standard level required by regulations on the protecting of personal data. Directions for further development of the implementation of the SIS and VIS in Poland have been presented in the conclusion.

Opis:
Blockchain-based cyber-physical systems (CPSs) and the blockchain Internet of things (BIoT) are two major focuses of the modern technological revolution. Currently we have security attacks like distributed denial-of-service (DDoS), address resolution protocol (ARP) spoofing attacks, various phishing and configuration threats, network congestion, etc. on the existing CPS and IoT architectures. This study conducts a complete survey on the flaws of the present centralized IoT system’s peer-to-peer (P2P) communication and the CPS architecture’s machine-to-machine (M2M) communication. Both these architectures could use the inherent consensus algorithms and cryptographic advantages of blockchain technology. To show how blockchain technology can resolve the flaws of the existing CPS and IoT architectures while maintaining confidentiality, integrity, and availability (the CIA triad), we conduct a holistic survey here on this topic and discuss the research focus in the domain of the BIoT. Then we analyse the similarities and dissimilarities of blockchain technology in IoT and CPS architectures. Finally, it is well understood that one should explore whether blockchain technology will give advantages to CPS and IoT applications through a decision support system (DSS) with a relevant mathematical model, so here we provide the DSS with such a model for this purpose.

Opis:
The emerging potentials in the electronics field, which facilitate the creation of complex projects with innovative functionalities, while maintaining low costs, are becoming even more appreciated by designers and engineers. In this manuscript, a telemetry system was designed and realized for monitoring main parameters of a racing vehicle. A STM32 Nucleo board acquires data from sensors installed on vehicle and transmits them to a base station. Acquired data are both stored on a SD card and wirelessly transmitted, for ensuring robustness/reliability of operation. The carried out tests confirm the truthfulness and compatibility of acquired data related to the vehicle parameters.

The authors of this paper have defined the notion of referential graphs which allow to model data and telecommunication networks in order to optimize them. Parameters of this type of graphs can be compared with parameters of modified chordal rings three and four degree. A description of the program developed for graphs of this type and its effects have been presented.
W artykule zdefiniowano pojęcie Grafu Referencyjnego, za pomocą którego można modelować sieci teleinformatyczne w celu ich optymalizacji. Zdefiniowano parametry takiego typu grafów, które zostały porównane z parametrami modyfikowanych pierścieni cięciwowych trzeciego i czwartego stopnia. Do modelowania poszczególnych przypadków opracowano program symulacyjny. Zaprezentowano opis tego programu oraz wyniki otrzymane przy wyszukiwaniu grafów referencyjnych dla szerokiego spektrum danych wejściowych.
