4.1  INTRODUCTION

The Internet of Things (IoT) came into the limelight in September 2003 with the

launch of a management vision of a supply chain that can be automatically tracked

by Auto-ID (Uckelmann et al. 2011).

With the advancement of technology, smarter and smaller devices have been in

demand along with the requirement for automation to reduce human intervention.

(Mattern and Floerkemeier 2010) These requirements have accelerated the develop­

ment of the IoT.

IoT leads to an interconnected world, where devices can be linked to the Internet

and controlled remotely. Such devices are referred to as smart devices. They can

interact with one another, among themselves, with other users or with other IoT

devices (Atzori, Iera, and Morabito 2010). IoT devices are mostly built to serve a

particular purpose and have limited resources, such as minimal communication and
