A Survey on Emerging Software-Defined Networking and Blockchain in Smart Health Care

Abstract

Abstract With assistance from Software Defined Networking (SDN) and Blockchain, networks have become more creative to build and maintain over the last few years. The inflexibility of modern network architecture is presenting researchers with a tough achievement. SDN replaces existing inescapable and complicated networks with a creative way of separating the control plane from the data plane and fixing those constraints, namely configurations done manually, monitoring, protection, usability, and functionality. This paper provides an overview of blockchain and SDN in healthcare. Various existing projects of their integration have been studied the benefits of the Blockchain provides security, privacy, integrity to the health care data has been discussed. The decentralization feature of blockchain provides access to data within and across the nation. Different use cases are discussed in the paper that provides the acceptability of blockchain and SDN in healthcare. This paper provides the overview and results that integration of blockchain and SDN in healthcare is a good research area and various initiatives have been taken to explore its integration.
