Synthesis of the topological structure of distributed terminal system for audio monitoring of users of local information spaces

A widespread use of multi-user interfaces, due to multimodality of traditional interpersonal communication, a transition to a polymerized presentation of information and systems, has allowed the creation of new approaches to their implementation based on distributed terminal systems. An approach to the synthesis of topological structures of such systems implemented in two stages is proposed in the article. The first stage determines a minimum set of communication nodes and their location based on the requirements for the availability of communication nodes for various categories of users and the globality of a distributed terminal system. The second stage determines options for constructing communication nodes and connections between them, which ensure the performance of audio monitoring functions of users of local information spaces while ensuring continuity of a bridge for different categories of users. A model example of the synthesis of a distributed terminal system for audio monitoring of two categories of users (adults and children) in the local information space (home), voice control subsystems of the "smart home" is presented. As a part of its solution, at each stage of the synthesis, the initial data are determined, a formal formulation of the synthesis problem is carried out, an algorithm for the solution and the results are presented. So the task of the first stage of the synthesis is a linear integer mathematical programming problem, solved in the model example by the simplex method, the solution of the second stage problem is based on the alternative graph formalization and the method of "branches and borders". The obtained results clearly demonstrate the capabilities of the proposed scientific and methodological tools for the synthesis of the topological structure of distributed terminal systems and the prospects of its use in the newly arising tasks of the technical implementation of new infocommunication technologies and services.
