Smart Cities: Survey On Addressing Challenges In Smart-Cities

Abstract

Technologically modern urban areas that use Information and Communication Technologies (ICT) to increase operational efficiency in sharing information with the public are known as smart cities. The fundamental objectives in smart cities development are sustainable environment, Quality of Life, and cost of living. To harmonious advancement of technology and the quality of citizen’s lifestyles. individuals are moving to smart cities from urban cities. The characteristics of smart cities are Quality of Life (QoL): mainly concentrates on financial emotional wellbeing of citizens, Sustainability: Engages with city governance, climatic change socio economic and citizens health, Smartness: Ensure the improvement of urban city standards, Urbanization: Enhancement of economic growth and interrelation policy formulation and realization. Four main pillars in smart city development are institutional infrastructure to integrate services and city operations with people, physical infrastructure to ensure sustainability, social infrastructure to bring awareness and economic infrastructure to flourish a smart economy. This survey aims to investigate and address the smart-cities challenges by comparing the existing solutions that are compatible with the advanced technological innovations for solving the smart-city challenges. Disaster management, e-Governance, e-transportation, waste management, cyber threats, data management and environmental safety are interconnected to analyze the challenges that arise with the exponential growth of urbanization and population. Technology acts as routine protocol between sustainability and flexibility in development of prospective smart-city infrastructure using Fog-Cloud techniques with Internet-of-Things(IoT)  support. Smart city is an application of IoT notion with an unceasing growth of population and urbanization have intensified innovative ways to handle city operations using Fog-computing and cloud storage network support intelligently with minimal human interaction in the generic architecture. Therefore, this paper aims to deliver the essence of smart cities in identifying the optimum technique for providing high data security and resource privacy with less latency and benchmark results. The researchers, those who are working to address the smart-urbanization challenges with technological enhancement to solve the key challenges, act as a real-world implementation mainstream gateway providing limitations and further challenges in smart-city through extensive literature survey.
