RFID and wireless sensor networks (WSNs) are two critical foundations of the Internet of Things (IoT). RFID systems are capable of identifying and tracking devices, but WSNs work together to collect and transmit data from networked sensors. This entails overcoming obstacles such as changing RFID systems with identifying capabilities into sensing and computational platforms and treating them as architectures of wirelessly linked sensing tags. This, together with recent advancements in WSNs and the integration of both technologies, has enabled the development of unique IoT applications. This article discusses these two technologies in detail, as well as the barriers and problems that must be solved. Several of these problems include energy harvesting efficiency, communication interference, fault tolerance, increased data processing capacity, economic feasibility, and an effective integration of various aspects. Additionally, two major themes in IoT are discussed: the coupling of RFID and WSNs to maximise their benefits and mitigate their shortcomings, and wearable sensors, which allow new and exciting IoT applications.
