Abstract

The article proposes an approach to evaluating the probabilistic and temporal characteristics of information interaction in Internet of Things networks. Designing Internet of Things systems involves solving tasks related to modeling information interaction processes. This enables the determination of optimal operating modes for such systems based on predicted traffic. The core concept of the Internet of Things lies in organizing the interaction between various objects in the environment, transmitting the information they generate, and ensuring a stable connection. Considering the novelty, fundamental characteristics, and complexity of Internet of Things systems, modeling and the development of relevant algorithms are key research tools during the design stage, which highlights the relevance of this work. The paper proposes a probabilistic model for establishing information interaction in an Internet of Things network with a mesh topology, developed using a multi-agent approach. The model accounts for the fundamental characteristics of Internet of Things and allows the evaluation of both absolute and probabilistic parameters of interaction. The model incorporates conditions corresponding to real-world information interaction processes, including faulty channels and access points, a limited number of reconnection attempts, and the presence of alternative routes.

To evaluate data transmission time, the Laplace-Stieltjes transform method is proposed. Its first central moment enables determining the average data transmission time within an established connection, while the probabilistic interpretation of the Laplace-Stieltjes transform allows assessing the probability of data delivery. The method provides an analysis of the time distribution for k-class data within an IoT network, based on given probabilities of errors occurring on route elements between all pairs of sensor devices. Using the Laplace-Stieltjes transform, it is possible to evaluate the permissible load on a route under a time constraint and, accordingly, select an optimal network self-organization algorithm.

Keywords: Internet of Things, IoT, probabilistic model, sensor device, sensor networks, information interaction.
