Intelligent Healthcare System Using Emerging Technologies: A Comprehensive Survey

Nowadays, health care is the most important domain to be analyzed by technology experts to replace traditional techniques. As healthcare applications have become technology-oriented, the upcoming technologies can be integrated to provide better, cheaper, and faster solutions. Wireless sensor networks, cloud computing, Internet of things (IoT) have come up with a solution mechanism for real-time monitoring of the body parameters of patients. Though these technological advancements have resolved many issues related to storage, scalability, availability, decision-making, and processing, it has many limitations that can be mitigated with the help of some advanced technologies to impose security and quality of service. In this paper, an exhaustive comprehensive study of 64 papers has been done to summarize different techniques used for intelligent healthcare systems and limitations which can open research directions for the developers and researchers.
