The aging of the population, the increase in the prevalence of chronic diseases and the limited availability of specialized medical personnel are global problems that pose a challenge to the administration of health resources. Not only is a change of model required in the way we use and access these resources, but to incorporate technology in the search for greater efficiency and impact in health care.The Internet of Things (IoT) promises to be the ideal element to catalyze these purposes, providing an easier, faster and more constant interaction to people who seek welfare and quality of care.This paper presents first a review of the different IoT applications oriented to the health monitoring, but only focused in applications protocols for devices with restricted capacities. Second, this research identifies common components in the review and proposes the main units needed in an IoT health architecture based on interoperability. At the end, a strategy design to dynamically select the IoT communication protocol using fuzzy logic is proposed for the authors of this paper.
