1 | A smart sustainable city is a city well performing in 6 characteristics, built on the “smart” combination of endowments and activities of self-decisive, independent and aware citizens [22] . | Economic growth, transport, mobility, environment, standard of living, governance |
2 | A smarter city uses technology to transform its core systems and optimize finite resources. At the highest levels of maturity, a smarter city is a knowledge-based system that provides real-time insights to stakeholders and enables decision makers to manage the city’s subsystems proactively. Effective information management is at the heart of this capability, and integration and analytics are the key enablers [23] . | Technology |
3 | Based on the exploration of a wide and extensive array of literature from various disciplinary areas we identify eight critical factors of smart city initiatives: management and organization, technology, governance, policy context, people and communities, economy, built infrastructure, and natural environment [24] . | Technology, governance, policy context, people and communities, economy, infrastructure, and the natural environment |
4 | A smart city is a city that has developed some technological infrastructure that enables it to collect, aggregate and analyze real-time data and has made a concerted effort to use that data to improve the lives of its residents. Smart city initiatives often involve three components: information and communication technologies (ICTs) that generate and aggregate data; analytical tools which convert that data into usable information; and organizational structures that encourage collaboration, innovation and the application of that information to solve public problems [25] . | Technology, organizational structures, collaboration, innovation |
5 | A smart city is a designation given to a city that incorporates information and communication technologies (ICT) to enhance the quality and performance of urban services such as energy, transportation and utilities to reduce resource consumption, wastage and overall costs. The overarching aim of a smart city is to enhance the quality of living for its citizens through technology. And how power of Blockchain can impact the functioning of a smart city. An approach is being presented on how Blockchain can be used on a smart city services platform to enable businesses and companies to participate in the smart city environment [26] . | Technology, urban services, transportation, citizens, quality of living, blockchain |
6 | The use of smart computing technologies to make the critical infrastructure components and services of a city—which include city administration, education, healthcare, public safety, real estate, transportation, and utilities—more intelligent, interconnected, efficiency and effectiveness [27] . | Technology, services, infrastructure, education, healthcare, public safety |
