The present study attempts to provide a consolidated conceptual framework concerning the Internet of Things (IoT) as a phenomenon that is becoming increasingly globalized. This process allows classifying the IoT into different nested functional subsystems within the networks a probability of and risk scale threat on the given sub-system or the networks as a whole. The paper also explains the IoT’s benefits, limitations, Integration of smart devices within healthcare systems, smart cities technologies, and Industry 4.0. It will address issues such as technologies, security, privacy, wearable technologies, and energy efficiency among others. Moreover, it elaborates on the technologies contributing to the expansion of IoT such as 5G, Artificial Intelligence, and cloud services. This paper concludes by proposing directions for future research. It also highlights a level of analysis where case studies provide conclusive insights, while the demand for innovation in IoT systems increases along with the associated risk levels.
