Faster development of sensor and network technologies is facilitating immense deployment
of Internet of Things (IoT) towards creating a smart world. In IoT, a massive number of
heterogeneous resource–constraint devices communicate with each other without any
human intervention and generate a huge amount of data. Unique research challenges
posed by IoT are fascinating the research community. This paper presents some of the
critical issues along with state of the art solutions towards them. In-depth discussion is …

Internet of things (IoT) is a widely used technology based on sensors. The main idea behind
IoT is the machine-to-machine communication in which every device is connected and
collects or sends information using sensor technology. IoT is implemented in various
scenarios like healthcare, environment monitoring, motion monitoring, agriculture, home
automation, and so forth. In this chapter, we present the basic knowledge on IoT its
architecture, technologies, protocols, and challenges related to security that IoT will …
