          Abstract

          With fastest development in communication technologies, Internet of Things (IoT) plays a key role with full maturity and its infancy. Rapidly, it has developed (growth) for large data transmission over the wireless communication. Hence, it is needed to manage system and full fill the market requirement for practical application. Many existing IoT has greatly centralized architectures that have many technical limitations. Examples of these limitations are cyber attacks. Hence, it is needed to find out new techniques for enhancement of data accessing with maintaining security as well as privacy. The solution for this problem is to make the combination of the IoT with block chain which gives a guarantee to sense data integrity. Integration of IoT and block chain resulted in immutable log, comprehensive and easy access. Here, this paper carried out the study of integration of IoT and block chain in relation with different issues, opportunities and application area.

              Internet of things (IoT) applications to fight against COVID-19 pandemic

              Background and aim The current global challenge of COVID-19 pandemic has surpassed the provincial, radical, conceptual, spiritual, social, and pedagogical boundaries. Internet of Things (IoT) enabled healthcare system is useful for proper monitoring of COVID-19 patients, by employing an interconnected network. This technology helps to increase patient satisfaction and reduces readmission rate in the hospital. Methods Searched the databases of Google Scholar, PubMed, SCOPUS and ResearchGate using the keywords “Internet of things” or “IoT” and “COVID-19”. Further inputs are also taken from blogs and relevant reports. Results IoT implementation impacts on reducing healthcare cost and improve treatment outcome of the infected patient. Therefore, this present study based research is attempted to explore, discuss, and highlight the overall applications of the well-proven IoT philosophy by offering a perspective roadmap to tackle the COVID-19 pandemic. Finally, twelve significant applications of IoT are identified and discussed. It has ultimately forced the researchers, academicians, and scientists to propose some productive solutions to overcome or confront this pandemic. Conclusions IoT is helpful for an infected patient of COVID-19 to identify symptoms and provides better treatment rapidly. It is useful for patient, physician, surgeon and hospital management system.
