Internet of Health Things for Quality of Life: Open Challenges based on a Systematic Literature Mapping

Internet of Health Things (IoHT) related papers has produced valuable knowledge concerning applications such as monitoring vital signs and predicting diseases. However, this knowledge is dispersed in the literature and, to the best of our knowledge, we could not find a recent study summarizing it. Thus, this work presents a systematic mapping conducted to organize the challenges regarding IoHT applied to QoL. As a result, we highlight a growing interest in developing health monitoring tools, but without many real-world validations. The most mentioned challenges were well-known IoT challenges, security and privacy, data science, and networks. Moreover, despite many studies discussing proposals for improving QoL, few papers sought to measure this gain, and none addressed the semantic organization of QoL data obtained from smart objects. Finally, it is expected for future a strengthening regarding elderly healthcare solutions, data science usage for personalized systems: smart models to predict health problems: and QoL continuous monitoring.
