The use of mobile ad hoc networks (MANET) with a nonline-of-sight (NLOS) communication channel in the UV-C spectral range from 200 to 280 nm is advisable in a number of conditions when traditional radio communication is ineffective (strong interference due the electromagnetic background interference, challenging terrain etc.).The detailed development of a data transport physical layer model is required to create reliable and efficient MANETs with a UV channel; the model is determined by the operating conditions of the networks.A hierarchical model for the conditioning of information signals has been developed, and also an optical transmitter and an optical receiver in order to provide their analytical description and further analysis; the model allows one to present various options for communication channels.Analytical expressions are obtained for the transfer function of the generalized hierarchical model for an arbitrary number of open levels of the hierarchy.The energy characteristics of the UV communication system are calculated at various noise levels depending on the geometric parameters of the UV channel: communication range and azimuthal deviation of the transmitter and receiver.
