Análise de desempenho de redes de satélites de órbita geoestacionária e órbita baixa para uso em aplicações de IoT com os protocolos MQTT e CoAP

Abstract

Currently, there is significant adoption of IoT devices, whether it be through smart switches in homes or sensors collecting data to assist in precision agriculture. As a result, there is a need to provide network infrastructure and internet access to meet the growing demand for connecting these devices. One of the most significant initiatives is the 5G network; however, there is a coverage problem for this technology. Additionally, many IoT applications require internet access in remote and inhospitable environments that are not served by terrestrial network infrastructure. In such cases, satellite connectivity becomes essential to ensure ubiquitous and continuous coverage for the devices. Recently, there has been a popularization of access to low Earth orbit (LEO) satellite connections. Therefore, this work conducted a performance analysis of satellite networks using the IoT application protocols MQTT and CoAP. The experiments were carried out on satellite links for geostationary orbit (GEO) with HughesNet and for low Earth orbit (LEO) with Starlink. The experiment assessed the feasibility of using GEO and LEO networks for IoT applications with the MQTT and CoAP protocols.
