Annotation:  A mathematical model for evaluating the efficiency of request service for real-time streams in a mobile ad hoc network is designed. To ensure high-quality transmission of audio and video streams, it is recommended to use the preliminary reservation of the required channel performance with the ability to buffer incoming requests. As an indicator of the evaluation of the effectiveness of the exchange of multimedia information, the probability of servicing requests for the transmission of real-time flows with a satisfactory quality is proposed. Based on the use of the characteristics of the main and additional realtime streams, the model takes into account the impact of the dynamism of the network topology on the efficiency of its functioning. The probability of servicing the incoming request for the transmission of the real-time stream is calculated for the most loaded network channel. The application of the model allows to justify the characteristics of the channels, which ensure an efficient exchange of real-time streams in a mobile ad hoc network

Keywords:  mobile ad hoc network, mathematical model, real-time streams, requests service, channel productivity reservation.
