Subject of Research. The paper studies one of the possible design and research approaches relating to wireless networks in the OMNeT ++ simulation environment by applying the INET framework. We show the modeling process of both the models themselves and their various operation modes. The model analysis methodology is considered on the example of a time diagram. Method. When considering the approach, the method of serial complication of the modelled wireless networks is used with reference to their operation features. The simplicity of the approach implementation is shown, as it uses ready-made components from the INET framework for models of wireless networks. The process of the time diagram research and the explanation of the simulation model behavior are demonstrated on the problem situation example. Main Results. We present the design method for wireless networks with the use of ready-made components from the INET framework. The redefining possibility of the composite module embedded components is demonstrated to create a model of the device that meets the necessary requirements. Possible operation modes of wireless networks are considered, both at the direct and indirect interaction of nodes through intermediate ones. The modeling approach for physical level and phenomena of interference is demonstrated. The approach for the problem situation research is considered involving the time diagram analysis. Practical Relevance. The proposed simulation environment allows for the study of design decisions in the design of the wireless networks. The applicability of the developed projects in real life is proved.
