DistArch-SCNet: Blockchain-Based Distributed Architecture with Li-Fi Communication for a Scalable Smart City Network

The winds of change are blowing toward the multibillion dollar global consumer electronics (CE) industry, which includes companies that are engaged in the manufacturing of smart devices to enable smartconnected vehicles, transportation, health-care systems, home automation, and smart industry in the smart-city network. The rapid increase in the number and diversity of smart devices connected to the Internet has given rise to concerns about scalability, efficiency, flexibility, and availability in the existing smart-city network. The imminent energy crisis, radiofrequency spectrum, and constraints on the lifetime of smart devices have also emerged as critical challenges. To address these challenges, this article presents DistArch-SCNet, the efficient, scalable, blockchain-based distributed smart-city network architecture enabled by the light-fidelity (Li-Fi) communication technique.
