This article provides a comprehensive review of all the architectures, technologies, protocols and data formats most commonly used by existing IoT platforms. On this basis, a comparative analysis of the most widely used open source IoT platforms is presented. This exhaustive comparison is based on multiple characteristics that will be essential to select the platform that best suits the needs of each organization.engAtribución 4.0 Internacional (CC BY 4.0)http://creativecommons.org/licenses/by/3.0/es/ArchitectureInternet of thingsIoT platformsIoT softwareOpen-sourcejournal articleopen access10.1016/j.iot.2022.100626
