Abstract

Nowadays, technology has been evolving rapidly. Due to the consequent impact of smart technologies, it becomes a ubiquitous part of life. These technologies have led to the emergence of smart cities that are geographic areas driven by advanced information and communication technologies. In the context of smart cities, IoT, blockchain, and fog computing have been found as the significant drivers of smart initiates. In this recognition, the present study is focused on delineating the impact and potential of blockchain, IoT, and fog computing on healthcare services in the context of smart cities. In pursuit of this objective, the study has conducted a systematic review of literature that is most relevant to the topic of the paper. In order to select the most relevant and credible articles, the researcher has used PRISMA and AMSTAR that have culminated in the 10 most relevant articles for the present study. The findings revealed that IoT, blockchain, and fog computing had become drivers of efficiency in the healthcare services in smart cities. Among the three technologies, IoT has been found to be widely incorporated. However, it is found to be lacking in terms of cost efficiency, data privacy, and interoperability of data. In this recognition, blockchain technology and fog computing have been found to be more relevant to the healthcare sector in smart cities. Blockchain has been presented as a promising technology for ensuring the protection of private data, creating a decentralized database, and improving the interoperability of data while fog computing has been presented as the promising technology for low-cost remote monitoring, reducing latency and increasing efficiency.

Highlights

The present study is focused on delineating the impact and potential of blockchain, Internet of things (IoT), and fog computing on healthcare services in the context of smart cities
Blockchain technology and fog computing have been found to be more relevant to the healthcare sector in smart cities
It is significant to note that there is a difference between m-health and s-health, as s-health aims to improve m-health by adding sensing abilities in smart cities. e healthcare sector has been experiencing a substantial increment in the volume of medical data of the patients shared between the insurance companies and the healthcare providers, which has resulted in the emergence of data-driven healthcare models [19]

Summary

Materials and Methods

E present paper incorporates a qualitative research approach in order to undertake a periodic and qualitative synthesis of the existing literature pertinent to the topic of blockchain, IoT, and fog computing for healthcare services in smart cities. The paper will be based on the synthesis of a number of credible and relevant journal articles and other studies on relevant topics from reliable and credible secondary data sources such as Google Scholar, EBSCOhost, JSTOR, and Emerald It implies that the selected material for the systematic review must correspond to the topic “blockchain, IoT, and fog computing for healthcare service in smart cities.”. It has enabled healthcare professionals and organizations to achieve accuracy and reliability in their
