Framework for Modeling, Procuring, and Building Systems for Smart City Scenarios Using Blockchain Technology and IoT

Abstract

Smart technologies have enabled our lives to be more comfortable and tangible day by day. In lieu of that, cities are also turning into “smart cities” through essential implementation of Internet of Things (IoT). This chapter presents a deep insight for modeling, procuring and building the smart city plan using IoT and a security framework using blockchain technology. To plan and develop state-of-the-art infrastructure of a smart city, the major domains on which IoT should consider are individual networks (such as education, transport, hospitals, energy, homes, business, etc.) connecting together with proper security and management. To fulfil the said requirement, it is highly desirable to integrate and manage physical and societal infrastructures ensuring efficient and best utilization of available resources controlled by IoT and secured by blockchain. The IoT system may connect myriad of nodes or machines of various kind capable to communicate with each other to get service whenever required. Use of IoT enables to utilize the wireless sensor networks but every node of the IoT system is considered to be prone to different attacks. The integration of technologies like internet of computing (IoC) and internet of everything (IoE) enabled the things more connected via various communication modes. Blockchain suggestively uses mathematical hashing and encryption tools for data security. By achieving innovative solutions, the citizens of the smart city will be able to collaborate with local governance for various services but not limited to subsidies under government schemes, health and safety, smart assets, education and employment, real estate, waste and sanitation, renewable energy.
