Location and visualization of the communication problems in a simulated Slovenian Armed Forces tactical radio network

Abstract

The article presents a concept of design, using the methods of simulation results, automatic analysis, and taking into account expert knowledge, and visualization of communication problems in the developed Tactical Player. The main emphasis is on the segment of simulation results evaluation on the basis of fuzzy sets, from which we have developed rules, the combination of which is used for evaluation of the quality of communication parameters between tactical radio stations. A special note should also be taken of the concept of modeling a tactical radio network and its characteristics, the mode of communication between radio stations, hierarchic organization, the problems of manual analysis of simulation results, etc. We present our solution for automatic analysis and the solution for visualization of problematic segments in the course of communication. The reader is acquainted with the problems of wireless communications and the key parameters influencing the connection between communicating entities, such as radio visibility, message transfer success, packet loss, deterioration of the signal–noise relation, etc. Because visualization of problematic time frames of the simulated communication on a virtual simulation field directly depends on the automatic analysis precision, we also used mathematical procedures (probability theory and possibility theory) as the basis of the fuzzy logic used. For a better understanding of the modeled prototype’s functioning, we also include a block scheme in the form of a process scheme, on the basis of which we can show the segments that are new and are a scientific contribution in the field of simulation techniques.
