The Internet of Things ( IoT )‐Based Smart Healthcare System ( SHS ), Using Blockchain Technique

ABSTRACT The WSN that has been developed for the Internet of Things (IoT)‐based smart healthcare system (SHS) utilizes the 5G and IoT protocols. WSN‐assisted IoT systems may be employed for many purposes. The primary criterion for every SHS application is energy efficiency, namely the reduced energy consumption of sensor nodes deployed in the field. In addition to that, SHS applications have crucial requirements for communication latency, security, and QoS performance. The suggested blueprint of an intelligent healthcare system comprises many tiers of Industry 4.0 (IoT) standards, including the edge layer, fog layer, and storage layer. The edge layer comprises a set of nodes that gather the patient's periodic information through various body sensors. The nodes that are collared red represent the patients that are wearing the body sensors. The medical data acquired at the edge layer is wirelessly sent to the fog nodes located at the fog layer. The fog node collects the information gathered by the edge devices in its immediate vicinity. Fog nodes encompass a variety of network devices such as routers, access points, gateways, and base stations. Ultimately, the storage layer is responsible for receiving data from the fog nodes to store and analyze it. Cloud storage services are utilized by several applications to access, analyze, and make decisions. As previously said, while creating and implementing a blockchain‐based healthcare system, it is important to solve the problems associated with the following terms: The data Storage: Given the extensive network of medical patients and hospitals connected by EHRs, it is imperative to employ a computationally efficient and robust cryptographic technique to establish the blockchain framework.
