Internet of Things: Architecture, Technologies, Applications, and Challenges

Abstract

A subset of cutting-edge information technology is the Internet of things (IoT). IoT refers to a network of physical objects with sensors attached that are linked to the Internet via LAN and WAN networking techniques. It is now commonly used to sense the environment and gather data in a variety of settings, including smart cities, healthcare, intelligent transportation, smart homes, and other structures. The IoT network architecture, core technology, and significant applications were outlined in this overview. The sensing layer, transport layer, and application layer are separated in the IoT network architecture. The essential technologies are embedded systems, network connectivity, sensor, and radio frequency identification (RFID) technology. IoT implementation in logistics still faces challenges despite the potential advantages. The utilization of technology in the IoT context is a topic with many open studies, which are also examined in this paper.
