Internet of Things (IoT) is all about the ability to sense things, understand and act according to the requirement of environmental conditions. The following information is about the potentials of IoT framework that everybody in business needs to realize, and its advantages over wide applications in daily activities.

Introduction

The developments of the Net Technology and Smart Sensor Systems have led to a new era of pervasive networks. An increase in users of the internet and advancements in ubiquitous computing enable the wide internetworking of everyday things. The Internet of Things (IoT) which is about “things” talking together, Machine-to-Machine (M2M) communications as well as person-to-computer communications by extending to the usage of “things”1. In the present technological scenario, the two terms, “IoT” and “Smart Things,” occur together frequently. The IoT gives rise to the smartness of interconnected things. In general, the words “IoT” and “Smart Things” follow each other in their respective application scenarios. The main objective of IoT is to have the ability to uniquely recognize, signify and access things anytime and anywhere in an internetwork, and this can allow the controlling of any “things” in an ideal situation.

In the present context, a paradigmatic approach for IoT applications has been presented to provide smart spaces and consisting of numerous independent Smart Things. The future internet focuses on integrating real world services provided by the IoT framework into a “mashup” of traditional services.

The adaptability of IoT modelling in day-to-day life activities makes for a variety of applications. The design and development of these applications depend on many different technologies that correspond to its realization for daily use. Initially, the use of the IoT was driven by the management of information through tags of Radio Frequency Identification (RFID) for tracking things, supervision and controlling of things, and automation of electronic payments in trade markets. The advancement of hardware technologies has brought up the development of the IoT by means of miniaturizing wireless devices, smart sensors/actuators and micro-controllers. Those technological advancements have inspired many schemes for refining the software of embedded devices. These have led to efficient optimization of M2M communications, providing very feasible and practical IoT-related applications. In the present context, a paradigmatic approach for IoT applications has been presented to provide smart spaces and consisting of numerous independent Smart Things. The future internet focuses on integrating real world services provided by the IoT framework into a “mashup” of traditional services1.
