The Role of Fog Computing in Enhancing IoT Efficiency and Real-Time Decision Making

Fog computing is also known as fog networking. It is a system where data processing occurs closer to the devices that generate the data, rather than sending everything to a distant cloud. It acts like a “middle layer” between the cloud and edge devices, such as sensors, smart devices, and machines. Fog computing is a method of bringing computing power and data storage closer to the devices that generate data, rather than depending solely on faraway cloud servers. By processing information locally, this approach helps reduce lag, improve response times, lowers bandwidth usage, and enables faster decision-making. With the growing use of smart devices and IoT systems, managing large volumes of data efficiently has become increasingly important . Fog computing supports this need and is proving especially valuable in areas such as smart cities, healthcare, manufacturing, and autonomous vehicles, where speed, reliability, and privacy matter most. This paper discusses the core concepts of fog computing, its benefits, and its rising importance in today’s technology landscape.
