IoT – principles and paradigms

Abstract

Every industry in the world is getting equipped with smart devices. The healthcare industry is enhancing its services via various smart wearable devices. The transport industry is developing customer satisfaction and goods security with the use of the intelligent transport system. The agriculture industry is pressing towards smart farming, like using sensors to improve the irrigation system and farm monitoring, and many more such domains are aiming towards an automated and smart environment. The education system is also leaping forward by introducing the concept of a smart university. Internet of Things (IoT) will play a crucial role in the pursuit of worldwide connectivity. In this paper, we have broadly discussed the basics of IoT, its applications, and various protocols and databases used. We have provided a brief insight into myriad of IoT applications, namely Smart cities, Smart security, Smart agriculture, Home automation, Smart health, Industrial control, Smart cars, and Smart university. Also, a comparison of protocols-CoAP, XMPP and MQTT-has been highlighted. For database connectivity, comparison among MongoDB, SQLite, and Firebase has been discussed. We aim to provide a succinct survey to all those who want to use IoT predominantly and specifically according to their requirements.
