Introduction The rapid development of wireless sensor networks (WSNs), which began to be used based on public communication networks (BPNs), involves the creation and implementation of new generation networks, which are self-organizing networks. This is especially true of the concept of the Internet of Things because the inclusion of things, both physical and virtual, in the customer base of communication networks leads to the growth of network terminals, which amounts to trillions. Today, technological progress has made it possible to start creating ultra-dense networks with ultra-low delays, the so-called flying sensor networks (FSNs) or the fifth-generation wireless communication networks. Therefore, the study of such networks is a very urgent task. The introduction of fourth-generation wireless networks based on the Long-Term Evolution (LTE) packet switching system has significantly increased an access speed and reduced time delays in establishing connections. LTE technologies made it possible to build heterogeneous networks, in which the coverage area of the LTE base station included both cellular networks and nodes of the BSS, automotive networks, etc. However, the development of the concepts of the Internet of Things, the Tactile Internet and Augmented Reality led to the need to create the fifth-generation networks, combining all possible resources of both fixed networks and cellular mobile networks. The new fifth-generation networks are associated with unmanned aerial vehicles (UAVs), that is why they are called FANETs (Flying Ad Hoc Networks). The main idea of designing such networks is based on the use of UAVs as head sensor networks and protocols of sensor networks for collecting information. In this case, the transfer of information is carried out through the protocols of public networks. Scientists around the world are actively conducting research in the field of WSNs and FSNs [1-5]. Basically, these works are related to the principles of building FANET networks and routing protocols, the development of search engines, the behavior of head sensor networks, as well as improving the connectivity of wireless sensor networks [6-9]. Since new generation communication networks consist of two components, ground and flying, the problem of their connectivity comes to the fore. Modern research is carried out in the field of new applications of the Internet of Things [10-12] and the Tactile Internet [13, 14], which reflect the development of WSNs at a new stage of their development. The paper analyzes a set of models and methods for the FSNs, which were built using the public UAVs based on wireless sensor networks ZigBee, 6L0WPAN, Thread, RPL, as well as devices for machine-to-machine (M2M) communication when implementing the Internet of Things concept [15-18]. The introduction of new technologies in the context of the development of ultra-dense networks, such as device-to-device (D2D) interaction technologies, allow not only to unload the network core by closing a significant proportion of traffic directly between devices, but also to reduce the round-trip delay in the provision of network services. In the field of D2D technologies, there is a large number of works, including research on D2D technology with network support [19-22].
