Matrix Digital Shadow of IoT Sensors Network

This paper presents the concept of a matrix digital shadow of an IoT sensor network. The differences between digital twin and digital shadow are discussed and the choice of the sensor network shadow concept is justified. A matrix description of such a network is presented and the concept of εk − neighborhood of sensor is introduced. Formulas for linear models of plus and star εk − neighborhoods are provided. Selected examples show the possibility of detecting and eliminating some security threats to sensor networks.
