Fog Computing in Healthcare: A Review

Abstract The Internet of things (IoT) connects multiple devices worldwide. It is a growing field in the healthcare system such as health monitoring and tracking, fitness program, remote medical assistance. With advent IoT based technologies healthcare, it can alleviate pressure on systems reduce cost, increase computing processing speed. Cloud was introduced to manage larger complex data environment. uses centralized cloud centers. central server manages for all devices. integration with has some major issues latency, bandwidth overuse, real-time response delays, protection, privacy. So concept edge fog came into existence overcome these issues. This paper review IoT-Fog-based model architectures, similar paradigm, issues, difficulties area finally, performance proposed assessed using iFogSim simulator.
