Construction of mobile ad-hoc networks (MANET) with a UV communication channel for use in military and other responsible and dangerous facilities is the promising and unexplored direction. Wireless optical communication systems in the ultraviolet (UV) range attract interest because of the unique ability to provide communication in the absence of direct visibility between the transmitter and the receiver (non-line-ofsight, NLOS) due to the scattering properties of UV radiation, which significantly expands the possibilities of using networks MANET. To create UV communications networks with high tactical and technical parameters, it is required to develop efficient algorithms for modeling such systems. The modeling task is highly difficult due to the complex nature of scattering in the UV communication channel. Based on the review and analysis of the shortcomings of the known analytical and numerical models, has been developed a high-speed algorithm for modeling such characteristics of wireless ultraviolet communication channels as attenuation, impulse response, frequency band. The developed algorithm based on the Monte Carlo method combines the advantages of wellknown analytical and numerical methods for modeling UV channels, making it possible to consider the elevation angles and azimuths of receivers and transmitters, the effect of an obstacle, to choose combinations with various numbers of transmitters and receivers of UV radiation. In addition, the algorithm performs the formation of parametric models of the UV channel based on the calculated characteristics of the channel. This will allow further using pre-calculated simulation results and significantly simplifying the calculation and multiparameter optimization in a setting process of the transmission mode of a wireless ad-hoc network with a UV channel.
