Smart Cities: A Survey on New Developments, Trends, and Opportunities

摘要

The continued growth of the population in urban areas has called for smarter cities for the 21st century. While great progress has been made in the last two decades in this regard, remaining challenges faced by city planners have forced them to pursue an alternative version of smart cities. Recent advancements in several technological areas like 5G communications, blockchain, and virtual/augmented reality have facilitated this process. This paper aims at providing a review of the definitions and components of current smart cities. It also discusses new developments, recent trends, and business opportunities.
