Fog Assisted-IoT Based Health Monitoring System

Cloud computing, from a very long time has played an integral part in processing, analysing and managing large quantum of data related to heath care system. Healthcare IoT devices are responsible for generation, processing and integration of large volumes of data which is then stored in cloud servers. Nevertheless, this results in huge compromise by delay in response time, which is due to centralized location of cloud servers storing related data. This lag in response time could prove vital while dealing with critical patients like those presenting with cardiac arrest or myocardial infarction and other quality of service (QoS), thus proving the inefficacy of cloud computing in meeting such intense demand. In order to avoid such delay, it necessitates introduction of a novel technology such as Fog computing. In the present publication, we propose, fog computing architecture and the rationale in switching from cloud computing to fog computing for prompt response time.
