VIII. CONCLUSION:
To sum up, in this paper we discuss some of the most advanced technologies that are expected to make cities more “smart” in order to improve the life quality of citizens. Further, we highlight Li-Fi as a promising future eco-friendly technology in wireless communication for the smart city, and we discuss the research questions associated with the evolution of smart city.
We strongly believe that the “smart city” paradigm is an umbrella term for various technologies that will continue growing in terms of infrastructure and communications, and that although the industry and real deployment of these technologies is progressing in enormous speed, the scientific community should follow all these inventions with the studies of implications and consequences that these technologies could have on different aspects of the future life, and start with searching for the solutions before the problems are encountered in practice.
