An Ontology-Based Approach for Distributed Multiagent Modeling of Radio-Technical Systems

Abstract

The ontology-based approach to multiagent modeling involves the implementation of a modeling system through the creation of ontologies. The IEEE 1516 Standard for Modeling and Simulation High Level Architecture is an example of a holistic implementation of an ontology-based approach to agent-based modeling. This work is devoted to a multiagent modeling system designed for modeling complex radio engineering systems (especially radar systems). This is relevant due to the need to replace part of the field tests of radio engineering systems with simulation experiments. One motivation for switching to the IEEE 1516 standard for a heavy multiagent modeling system, among others, is to ensure scalability, openness, and the multiple reuse of the developed agent models, which is completely logical, based on the existing well-developed and proven standard establishing rules for the interaction of models and the development of software interfaces. The general principles of the construction and architecture of the modeling system are given. The basic requirements for the main modeling agents and their role and place in the complex modeling system are shown, a special place among which is occupied by the simulator of the background-target environment. The possibility of combining two simulation schemes is also discussed: discrete-event and step-by-step. The fact is that the step-by-step scheme has the advantages of simplicity and clarity, and it is convenient to model processing algorithms and components of radio engineering systems. However, it is impossible to implement true autonomy and asynchrony of agents in it. Combining two modeling schemes allows you to combine their advantages.
