Abstract |
Currently, the direction of development and application of wireless optical communication systems in the ultraviolet (UV) range of spectrum is of particular relevance. An important advantage of the UV channel is the ability to provide reliable communication, protected from intentional suppression and interception, in the absence of line of sight between the transmitter and receiver. To create effective means of wireless UV communication, it is necessary to develop and analyze mathematical models of the UV channel at the physical and channel levels of information transmission. Many well-known numerical and analytical models of the UV channels do not take into account the particular geometry of the channel, relevant to mobile ad-hoc network (MANET): changing azimuths of transmitters and receivers when communication nodes are turning, communication mode with a different number of transmitters and receivers, etc. In the article mathematical software and software for analytical and numerical simulation of wireless UV communication channels in different terrain conditions at the physical and channel levels, allowing to investigate and analyze communication systems with a different number of transmitters and receivers of UV radiation, as well as to vary their spatial and angular coordinates, has been developed. To improve the reliability of modeling UV channels, known mathematical model of the channel based on the Monte Carlo method complemented by a model of obstacle, models of the geometrical arrangement and directional diagrams of the transmitters and receivers of UV radiation were modified. We obtained a number of simulation results of the losses of light propagation for different UV channels depending on the communication distance and angular parameters of transmitters and receivers: elevation angles, widths and azimuths of the directional diagrams. To assess a reliability of new numerical-analytical approach using the Monte Carlo method, comparative modeling with known analytical models was used. The perspective directions of further modeling of wireless self-organizing networks functioning on the basis of wireless UV communication channels are designated. |
