Smart health care is the recent buzzword in the healthcare environment. Involvement of technology in the healthcare domain provides a platform for remote real-time monitoring and self-management of patients’ health. The cloud computing is much utilized for developing technological solutions for an efficient smart healthcare system. Since cloud is a centralized environment, its response time becomes an issue in supporting latency-sensitive obligation in real-time applications. Most solutions in the e-health field depend on immediate decision making over real-time data where latency cannot be tolerated. Fog computing is a distributed infrastructure that overcomes this weakness of cloud computing by having the facility of local storage and processing in providing immediate response for decision making. Hence, thereby, it reduces the network latency and bandwidth usage by decreasing the amount of data …
