Chapter 4: Role of Internet of Things (IoT) in Enabling Circular Economy in Smart Cities

Internet of things (IoT) is the technology enabler in smart city adoption and creates circular economy (CE). The purpose of this chapter is to find out the relationship nexus between IoT, smart city and CE and its practical constraints in execution. This chapter elaborately maps the empirical evidence available in the literature survey of smart city development, information and communication technology (ICT) and CE. The contributions from outstanding scholars and current topics are analyzed using high citations index. The authors referred the topics with scholarly publishers and validated the data. Following that, significant technology subjects such as big data and analytics, as well as intelligent information systems, are individually examined. The findings are the challenges in implementing IoT and its interoperability capacity due to interlinking of different devices and systems. Another key challenger as well as drivers are data volume and quality, privacy, complexity and governance. The research can help policymakers, IT infrastructure provider, bureaucrats and all other concerned stakeholders to get sensitized on the implementation of IoT at smart city infrastructure. It also describes about the importance of collaboration and embracing open innovation (OI) while implementing IoT. This study is innovative in its approach and referred literature in the field of IoT, smart city, and CE by high citation index (HCI). It also researched about the various constraints in building CE through technology deployment and discusses about multilayer and multifunctional collaboration.
