A comprehensive study of security data for healthcare system using cloud of things based wireless body area network

The current search trend is entering the Cloud of Things. CoT aims to provide integrated and ubiquitous IoT services with IoT functions. However, realistic and time-consuming smart services require CoT architecture, which is energy efficient. This article explores architecture, sites and CoT implementation in the healthcare sector. It reviews the need for further efforts to achieve an energy-efficient CoT framework in the healthcare sector, taking into account energy efficiency, delay and quality of service. Researchers from academia and industry have begun exploring applications of blockchain technologies for healthcare. These applications include smart contracts, fraud detection, and authentication. In addition, as highlighted in this research report, there are many health care applications that have not been addressed by research into block chain experiments. In the health sector in particular progressively associated with data and correspondence innovation administrations One of the main administrations is far off patient observing, which permits medical care suppliers to follow, analyze and allude patients without remaining in the emergency clinic .The benefit of reducing sensing technologies is the ability to wirelessly transfer normal data to remote servers or install it on the patient's body. One of these technologies is called Wireless Body Area Network (WBAN).This survey explores clinical diagnosis, legal compliance, fraud prevention, and improving patient care.
