    Modeling a network of unmanned aerial vehicles
    (Lviv Politechnic Publishing House, 2021) Mykyichuk Mykola; Zihanshyn Nataliya
    The research concerns the methods of UAV group control in networks with duplex communication between nodes built on the “client-server” architecture. Such systems belong to self-organized networks with variable topology. It is important to study the allowable parameters of deviation from the task in the management of a group of UAVs and analysis of the network topology for the group flighting. The network was optimized according to the Ant Colony algorithm ACO. The application of different types of algorithms prevents routing problems in networks, such as ANTMANET, AntNet, ACODV and others. Methods of coordination of group joint actions are considered. A method is proposed by which the optimal number of UAVs operated by one operator can be determined and the traffic intensity of the communication channel is calculated, as well as the bandwidth and packet transmission delay are estimated.

    Calibration of measuring channels of non-dismantling cyber-physical systems
    (Lviv Politechnic Publishing House, 2021) Stadnyk Bohdan; Yatsuk Vasyl; Mykyichuk Mykola; Yatsyshyn Svyatoslav; Fröhlich Tomas; Mastylo Rostyslav
    The analysis of the concept of Open-Science Space is carried out. The existence of ways to achieve reproducibility and traceability of research results performed by a group of worldwide situated Cyber-physical system operators/supervisors is shown. Ways to ensure the efficient operation of Cyber-physical systems as complex technological non demountable objects with high requirements for metrological characteristics have been studied. To develop the scattered cyber physical systems, the portable stable-in-time code-controlled measures of physical quantities have been studied. They have to be metrologically confirmed in the laboratory before the delivery to the site of the measuring subsystem for its calibration.
