The Internet of Things (IoT) is a rapidly emerging paradigm in which physical or virtual objects equipped with sensors, actuators, processors and transceivers are connected with each other to enable communication among themselves. Some of the most significant IoT technologies are highlighted by reviewing state-of-the-art techniques, protocols and applications to bring about a striking difference in day-to-day life. This chapter is very inclusive in its coverage and exhaustively spans the major IoT technologies from sensors to applications. Artificial intelligence (AI) is a constantly and actively growing technology focused on intelligent agents which observe the environment in order to take appropriate actions. In the modern digitized world, AI machines perform creative and intellectual functions to uncover solutions by solving problems independently. Blockchains are tamper-resistant digital ledgers that record transactions in a distributed manner without the involvement of any central authorities or repositories. A community of users can record their transactions in a shared ledger; no transaction can be modified in the blockchain network once it has been published. The chapter provides an overview of blockchain technology that assists readers to understand how it works.
