Book excerpt: Due to the advancement of emerging technologies — Internet of Things (IoT), Artificial Intelligence (AI), and Blockchain (BC) — numerous aspects of our daily lives have witnessed remarkable progress. Further, with the involvement of these technologies (IoT, AI, and BC), the social life of a human is becoming more intelligent than ever. These technologies play a pivotal role in enhancing sectors such as healthcare, education, cities, households, agriculture, and industrial applications despite encountering certain challenges and complexities. Based on the contributions of these technologies, we provide a comprehensive survey covering various smart applications in different areas of everyday life. Firstly, we undertake an examination of state-of-the-art information, attributes, and prospects, with a specific emphasis on the literature that revolves around the technologies of AI, BC, and IoT. Further, we discuss the contributions of these technologies in the targeted areas and applications. Then, we efficiently introduce the integration of these technologies, including IoT-BC, IoT-AI-BC, and BC-AI, in the desired fields. Lastly, some open issues and future challenges have been analysed.
