The Internet of Things: A Vision for Smart World

The Internet of Things is a paradigm that involves physical objects with capabilities of sensing, information processing and communication through wireless or wired connection. These physical objects having embedded intelligence and hence decision-making capabilities act as smart things. The paradigm of IoT embraces various domains including sensors, information and communication technology, memory space, data analytics, machine learning and security and privacy mechanisms. The ‘things’ are constrained in terms of computing power, memory space and data rate and hence need innovative approaches to address the technical challenges present in the real-life implementation of the concept. This work presents a brief introduction to IoT concept, representative discussion on constituent domains and highlights of the technical challenges therein open for research community.
