Abstract	Blockchain, Software Defined Networking (SDN) and the Internet of Things (IoT) are the leading emerging technology all over the world. Blockchain is the main contributor to Bitcoin which aims to ignore the third party among the proceedings. On the contrary, the aims of the IoT network is connected with a massive number of objects over the internet. For smart cities, a distributed secure Blockchain-based SDN-IoT architecture has been proposed in this research paper with Network Function Virtualization (NFV) implementation. We have also revolved around the blockchain network which is a highly secured technology that provides good results in network performances, adaptability, privacy, security, accessibility, versatility, confidentiality, and efficiency. Moreover, we have presented a cluster head selection algorithm which aim is to select the desired head of the clusters. In addition, an approach has been also developed that is more efficient for generating a cluster head utilizing SDN-IoT. SDN-IoT with the NFV conception bring in benefits to the associated areas in terms of energy preservation and load equilibrating. In the projected architecture, the Blockchain network allows more prominent security of each network layer relative to the schematic network. © 2019 IEEE.
