Internet-of-Things is the future of connectivity that has turned the physical
world into smart objects. The practical feature of Internet-of-Things is to combine all
objects, rendering them dependent on a shared infrastructure, in such a manner that
humans can regulate them as well as monitor their status. Internet-of-Things is a
physical object network that is embedded with hardware, software, sensors, and
networking to allow objects to share data with the connected devices. This chapter
details the Internet of Things, vision challenges, and various intelligent applications in
sensor-enabled networks. The wide-scale application of the Internet would significantly
affect how computers and objects engage in real-life scenarios. This chapter aims to
highlight the perspective of some novel technologies and innovative implementations
for the protection, welfare, and privacy concerns due to the Internet of Things. Some
critical sensor networks, which represent the most used sensor networks in many
domains, such as Smart Applications, are included in this introduction section. A
literature study on Internet-of-Things has been conducted for different aspects, such as
infrastructure, implementation problems, etc. The authors offer several other
applications that are significant. Future research directions for Internet-of-Things have
been outlined in the study to equip novel researchers with the assessment of current
status and to build upon them with creative ideas.
