Abstract

With the rapid advancement of technology, everything is transforming into smarter versions. The term smart city means a technologically strengthened and advanced version of the city. Smart cities utilize digital information and techniques for improving services like performance, quality, etc. Big data technology and methods are utilized for handling the vast volume, high velocity and wide variety of data related to cities. This chapter discusses the big data utilization for making smart cities and also throws light on various applications where efficient analysis of services can be carried out using Big Data techniques. The main objective of this chapter will be to provide knowledge of big data implementation for the smart city and its services. This chapter will also investigate various prospects, benefits, and challenges of absorbing big data utilization for smart cities. It will also discuss some case studies related to big data applications for smart city services. It will also propose some open issues related to big data implementation for the smart city.

Smart City

Smart cities utilize digital information and techniques for improving services like performance, quality etc. Smart city helps in reducing cost and consumption of resources and active engagement of residents. The main goal behind development of smart city applications is improvement of management techniques of urban flows and also allows real time data response and various challenges associated with it. Smart city helps in enhancing the process of decision-making combining Information Technology. Smart city characteristics are as follows:

  • •

    Instrumented City: City’s data of data sources are sensed and measured

  • •

    Interconnected City: Consists of physical phase and logical phase. Physical phase refers to the networks which integrates systems and also attach devices. Logical phase deals with the combination of data from various sources and also mentions relationships between data.

  • •

    Intelligent City: Utilizes various advance logical techniques to set perceptions for events of city and tools for visualization to envisage behavior of city.

Big Data

Big Data is a technology for describing vast volumes of data both structured as well as unstructured. Since the volume of data is huge that’s why it turns to be tricky to process data using conventional data management techniques. The big data term involves properties like sorting data, streaming live data, despite of format of data i.e. text, audio, video, etc. Big data characteristics are as follows:

  • •

    Volume: data size or amount of data.

  • •

    Variety: data from various sources in structured as well as unstructured format.

  • •

    Velocity: the rate of flow of data from various sources where flow is huge and continuous.

  • •

    Veracity: data uncertainty which deals with quality, accuracy, reliability of data.

Big data characteristics reveals large potential regarding advancement and possibilities are continuous which are bound to the tools and technologies available. In order to attain goals and services in smart city big data entails analysis of tools and techniques which are categorized efficiently and effectively.
