Purpose of research. Computing networks of a plurality of processor modules have existed for a long time, however, with the development of wireless technologies, the possibility of high-quality and inexpensive implementation of the idea of real-time reconfigurable computing networks (RRTCN) has emerged. The purpose of this work is to select a wireless data transmission network for the RRTCN and create an algorithm for the dynamic selection of the "master" processor module.Methods. The research methods of the work are based on the definitions of the theory of sets and graphs. In particular, a grapho-theoretical approach to distribution is taken as a basis, supplemented by the introduction of a system of criteria for a reconfigurable real-time computing system based on a wireless data transmission protocol.Results. In this paper, the most suitable data transfer protocol for the local RCSRV is selected, a developed mathematical model of changing a real-time computing system built on a wireless protocol is presented, and an algorithm for selecting the processor module (PM) of the RCSRV "master" is developed. The novelty of the work is the use of the distance matrix for the mathematical description of the change in the RRTCN and its use to determine the PM of the "master" in the aircraft.Conclusion. The developed algorithm for choosing the PM of the "master" RRTCN and the mathematical model of changing the position of the PM in a real-time computer system built on a wireless protocol allows organizing the optimal choice of the PM of the "master" in a reconfigurable computing system. On the basis of the presented mathematical model, in the future, it is possible to create a full-fledged mathematical model of the RRTCN and an algorithm for placing tasks in it.
