In computer science and telecommunications, WSN are an active research area. In the paper an analysis of models of WSN with random access is presented. In these models, the parameters characterizing the network can be random. We presented the methodology of selection of the network model for practical application. We give an example of application of this methodology for the selection of the network model that supports the safety of maintenance work on the building.enWireless Sensor NetworkPoisson processprobability of collisionmethodology of network model selectionGeneralized models, construction methodology and the application of secure wireless sensor networks with random network parametersУзагальнені моделі, методологія побудови та застосування захищених безпровідних сенсорних мереж з випадковими мережевими параметрамиОбобщенные модели, методология построения и применение защищенных беспроводных сенсорных сетей со случайными сетевыми параметрамиArticle004.7:62-519:621.391 (045)
