The Internet of Things (IoT) has emerged as a transformative paradigm, bridging the physical and digital realms through the interconnection of smart devices, sensors, and systems. In recent years, IoT has catalyzed innovation across critical sectors such as healthcare, agriculture, and manufacturing, driving significant improvements in efficiency and safety. This paper presents a comprehensive review of recent advancements in the IoT landscape, examining its core enabling technologies, diverse applications, and the primary challenges impeding its widespread adoption. We analyze the pivotal role of 5G, edge computing, artificial intelligence (AI), and blockchain in enhancing IoT capabilities and performance. Furthermore, we address persistent challenges related to security, scalability, interoperability, and privacy, outlining potential solutions and providing a perspective on future research directions for robust IoT development.
