Modelling and Performance Evaluation of IoT Network During the COVID-19 Pandemic

Abstract

Information from COVID-19 IoT (Internet of Things) devices is greatly important when it is fresh. However, the packets’ collision problem slows down the speed at which this information reaches, resulting in a wider spread of the virus. In this paper, we address this challenge by giving priority to COVID-19 IoT devices over consumer IoT devices. We propose a two-dimensional Markov chain for modelling the IoT network including COVID-19 IoT devices, then we derive the performance metrics. Our numerical results show a significant improvement in the performance of COVID-19 IoT network in terms of throughput and average delay. Our approach provides a reliable and fast wireless connection of COVID-19 IoT devices to the gateway.
