Model-Oriented Design of a Wireless Sensor Network

Abstract

The wireless sensor network (WSN) is the basis of a complex technical monitoring system. The monitoring system corresponds to the concept of “Industrial Internet of Things” (IIoT). The monitoring goals may be different. The organization of work on the project in model-oriented design consists of the following stages: define wireless sensor network requirements; modeling of WSN and WSN the individual subsystems; designing connectivity and interaction of WSN nodes; WSN simulation and implementation; checking and testing the WSN. The main features of model-oriented design in WSN design: development of simulated specifications; design and simulation of WSN with components of different physical nature; continuous testing and verification. When using model-oriented design, the specification is presented as a model in addition to the text requirements. The same set of models is used for the entire group, as well as a complete model of the entire system and external conditions. Different system views are used to describe a single WSN object. For example, the spatial location of WSN nodes, the WSN topology, the communication connectivity of WSN nodes. This is the main difficulty of the project. Model-oriented design combines various system representations of a single object-WSN. As a result, you can create a digital model of the entire object. The effect of using a digital model is that it is a tool aimed at making optimal decisions. Using a digital model is a transition to a data driven technical culture - making decisions based on modeling and achieving the final result.
