Retraction: Fog Computing-based Internet of Things and its Applications in Healthcare

Abstract

Internet of Things is the most revolutionary and attractive technology of today, which employs a combination of sensors, embedded systems, software and artificial intelligence. These devices are usually coupled with the cloud to produce significant insights. However, the cloud comes with its own issues such as network latency and jitter, which makes it inappropriate for delay-sensitive applications such as healthcare. Hence, a novel paradigm came about known as fog computing, in which computation is carried out at a data collection edge/source. In this paper, we have studied fog computing in a bottom-up fashion, starting from its key features, merits, and then an architecture to show that its integration into a traditional cloud-based IoT system makes it suitable for latency-sensitive applications. We have further made a deep dive into how fog-based IoT systems can be utilized in the field of healthcare, studying the architectures for context-sensitive and at-home healthcare monitoring.
