The capabilities of existing intelligent decision-making systems are very limited, so for
the successful solution of a wide class of tasks based on unmanned aerial vehicles (UAVs) reliable communication with the group of aircraft is required. For communication between individual UAVs, as well as UAVs with a ground station, Flying Ad Hoc Networks (FANET) and flying sensor networks (FSN) are used. Known works devoted to the development and research of such networks consider predominantly radio communication at the physical level. Telecommunications networks that use radio communication at the physical level are ineffective in a number of conditions (the presence of high obstacles in the conditions of dense urban development or difficult terrain, a high level of external electromagnetic background, the action of electronic warfare). Optical communication systems of the infrared and visible range function only when there is a line of sight between the transmitter and receiver, which makes it difficult to communicate with mobile objects ? unmanned aerial vehicles (UAVs). It is promising to use optical communication in the UV-C range in the absence of direct visibility between the UAV network nodes. The disadvantages of this type of communication are a limited range (up to 4 km), as well as a low bitrate (tens to hundreds of kbit/s). To reduce the disadvantages of radio frequency and optical UV-C channels in communication networks with UAVs, it is proposed to perform their aggregation. The relationships were obtained and modeling of UV-C and RF communication systems with UAVs was performed, and the conditions for the best use of UV-C and RF channels in a complex urban environment were determined. |
