Abstract

The article is devoted to the description of the methods of modeling wireless networks in the OMNeT++ environment using the INET Framework. The article discusses the main concepts related to the modeling of wireless networks, and also describes the main requirements for models of wireless networks. Next, the article examines the OMNeT++ simulation environment, its main characteristics and advantages compared to other simulation environments. The article considers the main components of wireless network models, such as network layer models, physical layer models, and radio channel models. For each of these components, the article considers modeling methods and describes possible nuances associated with the choice of various modeling parameters. The article offers a detailed description of the structure of the wireless network model using the IEEE 802.11 network as an example. This part of the article covers concepts such as a node, an access point, and the different types of packets transmitted on a network. The article also discusses methods of modeling various types of network protocols, for example, MAC protocol, network layer protocol, and others. The final part of the article deals with testing wireless network models and their analysis. The methodology of testing and comparing different models is described, as well as the issue of analysis of modeling results and their interpretation is considered. In general, the article offers a detailed description of the methods of modeling wireless networks in the OMNeT++ environment using the INET Framework. One of the possible approaches to the design and research of wireless networks in the OMNeT++ simulation environment using the INET framework is considered. The process of modeling both the models themselves and their various modes of operation is shown. The methodology of analyzing the model's operation using the example of a time diagram is also considered. When considering the approach, the method of sequential laying of simulated wireless networks was used, taking into account the peculiarities of their operation modes. The ease of implementation of the approach is shown, in which ready-made components from the INET framework are used for modeling wireless networks. The method of designing wireless networks using ready-made components from the INET framework is presented. The possibility of redefining the built-in components of the assembled module to create a device model that meets the necessary requirements is demonstrated. Possible modes of operation of wireless networks with direct interaction of nodes, and with indirect interaction through intermediate nodes are considered. An approach to modeling the physical level and the phenomenon of interference is demonstrated. The approach of studying the problem situation, which consists in the analysis of the time diagram, is considered. Practical significance. The proposed environment of simulation modeling allows to conduct research of design solutions during the design of wireless networks. The expediency of using the developed projects in project activity is substantiated.
