The term "smart city" means a city that makes full use of IT systems to increase operational efficiency, disseminate information to citizens and visitors, and improve the quality of services public.
Improving data access is another key element of the Smart City concept. Proponents of smart city projects advocate allowing citizens access to a large amount of municipal data, in order to increase civic sense and enable citizens to develop their own technologies with this information.
Smart and sustainable city:
The ITU-T Focus Group on Smart and Sustainable Cities has forged this new term based on the analysis of around 100 different definitions. At its fifth meeting held in Genoa (Italy) on 19 and 20 June 2014, the Focus Group on Smart and Sustainable Cities agreed on the following definition: "A smart and sustainable city is an innovative city using information and communication technologies and other means to improve the quality of life, the efficiency of urban management and urban services and competitiveness while respecting the needs of current and future generations in the economic, social and environmental domains.»
«ICT infrastructure is the nervous system of any smart and sustainable city; it coordinates the interactions between the different components and the physical infrastructure. It is the base from which the different intelligent services can operate in an efficient and optimal way», says M. Kondepudi.
The adoption of the smart city concept is partly based on the emergence of technologies and IT trends, such as the deployment of the Internet of Things architectures, capable of collecting data from remote devices and mobile devices connected to the Internet. Wi-Fi networks and the proliferation of GPS devices that constantly capture and transmit location data.
