Traffic modeling and analysis in channels of telecommunication subsystems of complex security systems

Abstract

In the article, necessity of monitoring telecommunication subsystems of complex security systems is substantiated. A simulation model is proposed, which makes it possible to form elements of a time series, in the role of which the moments of the beginning of the transmission of messages act. The possibility of forming both stationary and non-stationary flows of events is foreseen. The results of research on the main methods of time series analysis are presented. It is shown that the used approaches do not allow detecting possible anomalous traffic states with the necessary efficiency and reliability. It is proposed to consider the telecommunication system as a dynamic system for the evaluation of different traffic states. Analytical expressions for the formation of dynamic variables, on the basis of which phase portraits are formed, are presented. The obtained results of the experiments confirmed the informativeness of the proposed variant of traffic display. It is shown that the assessment of the state of telecommunication systems using phase portraits makes it possible to detect abnormal traffic conditions, as well as to predict the behavior of a dynamic system in the future.
