An examination of fog computing and its applications in modern technologies

Network components between devices and the cloud carry out application-specific functionality in a fog computing architectural style. Healthcare is currently undergoing some of its most fundamental transformations. Wireless sensor technology is one of the forces behind these changes. In addition to providing access to a greater variety of biometric characteristics, sensors are growing smaller so they may be worn without interfering with daily activities. Fog computing's topology, or the geographically dispersed nodes that carry out computation and provide storage and network services, is its defining feature. Access points, routers, and network gateways can incorporate fog computing resources in addition to the standard network features. Instead of transferring IoT data to the cloud, the fog processes and stores it locally at IoT devices. The fog offers services that are more responsive and of higher quality than the cloud. Fog computing may thus be the greatest option for enabling the IoT to offer effective and secure services to a large number of IoT users. By emphasizing the advantages and implementation difficulties, this article demonstrates the state-of-the-art of fog computing and its integration with the IoT. Right now, healthcare is undergoing some of the most significant transformations ever. Wireless sensor technologies are one of the main reasons for these changes. Many of the objects we use on a daily basis may soon be able to connect to the Internet and communicate with one another without the need for human intervention, thanks to the Internet of Things. This review paper examines fog computing and its applications in Healthcare, Cloud Computing and Internet of Things.
