23.1 INTRODUCTION

The Internet is best understood as a globally distributed network of voluntarily interconnected devices that can communicate with each other over well‐defined protocols to enable business operations. Until recently, the devices connected by the Internet have predominantly been computational (e.g., personal computers) or communicative (e.g., smartphones). In contrast, the Internet of Things (IoT) is a network of physical objects containing components that can collect data about the physical objects and exchange this data with other objects in the network. The physical objects communicate with each other in order to function as a collective unit. The electronic components embedded in these physical objects that collect and exchange data about these objects are typically designed for a single purpose based on the properties and interactions that are relevant to the physical objects; for example, the devices in a Smart light bulb need to be concerned with understanding and manipulating only a few attributes like hue and brightness of the light generated. Consequently, compared to multipurpose devices, the devices in IoT networks tend to require significantly less processing power and capacity, which also makes it possible to utilize these devices in significantly larger numbers. The number of devices in the IoT network is estimated to be an order of ...
