The work is devoted to the development of the method of structural adaptation of digital radio networks based on new generalized indi-cators of the evaluation of the effectiveness of information exchange in conditions of high input traffic and exposure to interference.
The analysis of publications in this field and the results of the conducted studies show that the parametric adaptation contour based on the use of private indicators of information exchange quality gives the least effect of management for maintaining the required quality of operation of the digital radio networks (DRN), and the mechanisms of the algoritmic level ensure only the process of deducing the DRN in the area of effective functioning in the sense of information exchange. Therefore, the application of methods and algorithms of structural adaptation of the DRN to the conditions of information exchange is an actual and practically important task in order to ensure the high-quality functioning of the DRN in the context of sudden changes high input traffic.
The realization of structural adaptation in the DRN requires the use of a formed database or reserve topolodies, including a universal (global) indicator of the effectiveness of information exchange and strict adaptation criteria. As such an indicator, the efficiency coefficient (EC) of information is proposed taking into account the exposure to interference.
In this work, the authors proposes a new method and block diagram of the algorithm of structural adaptation, which uniquely determines the conditions for choosing the reserve topology of the DRN and for changing physical structures taking into account and interference situation. Analysis of simulation result proves the practical realizibility and working capacity of the developed method, in the course of which definitely: a region of high information efficiency, maximum values of EC, regions of forward and backward transition, specific values of the points of changes of srtuctures.
