In this chapter, the researchers have reviewed and assessed the IoT issues and challenges in the implementation of a smart city in the Indian scenario. They extensively acknowledge that the IoT advancements and applications are still in their emerging stages. Moreover, there are many issues and challenges associated with IoT such as legal, regulatory, and economic queries, and infrastructural development, security, and privacy issues. In addition, the study also revisits and explains the network communication models used in establishing connection with electronic devices and the Internet through different layers. The applications of the IoT and blockchain concepts in building future cities and information systems and hypothesized models on EVM and UID cards have also been discussed. Further, the study presents a hypothetical model explaining the device as it relates to cloud communication for monitoring water usage and pumping. The study adds to the existing literature on the IoT and creation of the smart city. The chapter states that smart cities and IoT innovation solutions will positively affect the growth of the country, although its reception rate among countries is moderately low because of the absence of trust, inadequate innovation, and limited access to technological infrastructure. To ensure that this new innovation works, all governing bodies should make effective policies. For the administration of advanced technology, first support the development of progressive networks by giving the required motivation and freedom to the communication industry. The chapter concludes by discussing the futuristic approach of IoT for creating smart cities in India and the challenges in the implementation of technologies.
