Internet of Things and Its Relevance

Abstract

The internet of things (IoT) model connects physical devices to the virtual world and enables them to interact. It enables smart devices to communicate with other devices to exchange information. To link a wireless network or cloud network, it takes the help of several technologies such as radio frequency identification (RFID), wireless sensor network (WSN), near field communication (NFC), ZigBee, and others. The IoT requires a standard architecture and protocol stack to establish links between the devices. This chapter provides a brief introduction, pillars, the evolution, architecture, application of IoT, and issues related to IoT implementation in real life.
