Heterogeneity in IoT-based smart city designs

Smart city is a strategy of supporting a new way of living using data collected from different types of electronic devices. Subsequently, such data are analyzed and utilized to enable efficient resource usability and service optimization. Various applications, such as traffic planning, crowd monitoring, public health care, security, economy, and urban planning, are elaborated in smart cities. Thus, various requirements are needed to incorporate and facilitate efficient development of these applications in the smart city design. Smart cities can be distinguished via the requirements supporting these applications. This study establishes the requirements of smart cities in relation to the involved applications and their influence on the smart city design. Moreover, this research provides a list of smart city requirements and discusses the potentials of various network architectures to facilitate such requirements. The existing smart city designs are evaluated and compared on the basis of the requirements and architectures. © International Association of Online Engineering.
