The ICT is becoming increasingly pervasive to urban environments and providing the necessary basis for sustainability and resilience of the smart futuristic cities. ICT as the prime enabler for smart cities transforms application specific data into useful information and knowledge. From the ICT perspective, the possibility of Realisation of smart cities is being enabled by smarter hardware (smart phones, sensor nets, smart household appliances, etc.), which can organise in an 'Internet of Things' (IoT) and causing become a major source of ever increasing user and environment Specific Data. Use of cloud,Fog or edge computing can be considered as a common platform as service for managing cross-departmental city data and providing necessary computation power to generate required integrated information intelligence for decision making and policy development.

Smart cities can benefit from such data (often open data). ICT tools for a smart city often deal with different application domains eg land use, transport, energy, and rarely provide an integrated information perspective to deal with sustainability and socioeconomic growth of the city . And information using Big, and often real-time cross-thematic, data collection, processing, integration and sharing through inter-operable services deployed in a cloud, fog or edge environment. However, such information utilisation requires appropriate software tools, services and Technologies To collect, store, analyse and visualise large amounts of data from the city environment, citizens and various departments and agencies at city scale to generate new knowledge and support decision making.

单词the above context, the real value of smart city data is gained by new knowledge generation and by performing context based data processing and analytics using various data mining, machine learning or resolution methods. This becomes critical when applied to large scale or real time data In addition, privacy and security issues must be dealt with to avoid sharing intrusive details of participants. , eg increasing use of Incled, led related to use of Cloud, Big data,Real-time processing, IoTs are encouraged.
