ДОСТИЖЕНИЯ И ПЕРСПЕКТИВЫ» New Generation Сonnection latency reducing is limited by the physical nature of the signal propagation environment, where the speed does not exceed the speed of light. Further development of new generation networks has led to the emergence of the communication networks, called Ad-Hoc networks, or target networks. Their feature is the absence of a permanent topology structure, which consists of autonomously working nodes. Each node can communicate with the neighboring nodes, combined into a self-organizing network. In the event of failure of one or more nodes, the remaining nodes will be able to establish new routes in order to correctly deliver the necessary information. Figure 3 shows three types of Ad-Hoc networks: mobile target networks MANETs (Mobile Ad-Hoc Network), vehicle target networks VANETs (Vehicle Ad-Hoc Network) and flying target networks FANETs (Flying Ad-Hoc Network). Mobile networks are self-organizing peer-to-peer wireless networks with an inconsistent topology, each node can move along any trajectory, and all these topology changes must be communicated to the rest of the nodes to maintain a correct routing of data between them. They are indispensable for rescue operations after natural disasters or catastrophes. Automotive target networks provide vehicle-to-vehicle communication via V2V communications (Vehicle- to-Vehicle) or by connecting to nearby V2I (Vehicle-to-Infrastructure) fixed infrastructure. Flying targeted FANETs are of particular interest, as they have a number of advantages over others. This is a higher level of mobility, independent operability, thanks to Peer-to-Peer connections and greater distance between nodes. To increase the distance and range between nodes, it is possible to establish communication with a satellite on each drone (Backbone UAV), which leads to a sharp rise in the cost of servicing such networks. The limitation in the communication range can be solved by organizing communication channels between the UAVs. While some UAVs will communicate with a ground station or satellite, other UAVs will be able to receive data without direct communication with the ground station, but through communication with neighboring devices. Such networks are called FUSNs (Flying Ubiquitous Sensor Networks).
