This layer consists of high-end processors, large and high-speed data storage, and Network Interface Card for communication over internet. The patient health data are very critical data a normal considerable amount of latency can cost lives, example of such type of data is Myocardial Infarction where latency of seconds can cause serious damage Singh et al. [26]. So, we cannot rely only on cloud for data processing and analyzing critical time sensitive data. In handling these types of data, we require analysis, processing, and storage as close as possible to the devices where data is generated Badidi et al. [23]. Thus, need of fog computing arises here, and it processes, analyzes, and stores (for further use) health-related data which is very time-sensitive in nature Kraemer et al. [28]. This layer also filters, compresses high volume raw data, and passes to next layer (cloud computing layer) for big data analytics purposes.
