Internet of Things ( IoT ) Fundamentals

Abstract

In the modern era, a plethora of things are being connected to each other using underlying network technologies with an aim to promote the paradigm of the Internet of Things (IoT). In general, the IoT vision can be seen in terms of things centric and Internet centric. From the evolutionary perspective of IoT, it seems that IoT in different eras has been regarded as another name of a particular technology. Therefore, the term IoT is associated with other technologies in literature, i.e. embedded system, Machine‐to‐Machine communication, Cyber Physical Systems, Wireless Sensor Network, and Web of Things. In this chapter, from the pool of proposed IoT architectures, the functionality of each layer of the following IoT architectures has been explicated: three‐layer IoT architecture, five‐layer IoT architecture, six‐layer IoT architecture, and seven‐layer architecture.
