The article is devoted to solving an urgent scientific and technical problem. It consists of developing an algorithm. This is used for estimating the recommended buffer size of requests of transmitting data streams. So, this has been done in a flying self-organizing network. Therefore, it is used to ensure geoecological monitoring of the resources of the agro-industrial complex. However, Studies have shown that to ensure the required quality of data streams transmission. Thus, it is advisable to carry out preliminary reservation of channel performance. Hence, it is possible to increase the likelihood of servicing requests of the transmission of data streams, as well as to increase the load of network channels by buffering incoming requests of the transmission of data streams. So, the developed algorithm makes it possible to substantiate the decisionmaking to increase the channel load and ensure an acceptable delay in the start of data streams transmission. Therefore, it has been done in a flying self-organizing network. Hence, the studies carried out the correctness of the algorithm and the expediency of its application. However, in practice the process of tuning the channels of a flying self-organizing network has been carried.
