An Intelligent Vaccine Distribution Process in COVID-19 Pandemic through Blockchain-SDN Framework from Bangladesh Perspective

Currently, vaccine distribution is the most concerning issue of Coronavirus (SARS-CoV-2) diseases in every stage of peoples properly. There are several strategies is proposed by the researchers. Still, the public is facing various difficulties in taking the vaccine. However, the current technologies such as the Internet of Things (IoT), Software-Defined Networking (SDN), and Blockchain (BC) are the intelligent solution for vaccine distribution efficiently. In light of these considerations, in this paper, we propose the “DistVAC-COVID” architecture incorporating a distributed Blockchain-based SDN-IoT framework for COVID-19's vaccine distribution considerably. In the presented system, the SDN benefits to divide the entire network into two distinct planes such as the data and control plane for distributing COVID data smartly. Further, a distributed Blockchain provides the desired system to be prominently secured and more confidential. Therefore, the “DistVAC-COVID” model combining SDN, IoT, and BC can be handled by several COVID-19 zones-red, hazard, and green securely. Finally, we evaluate the “DistVAC-COVID” architecture via an experimental evaluation process and show the effectiveness of the suggested solution in comparison with baseline system.
