Web-Based IoT Application Development

Introduction

Wireless Sensor Network (WSN) is an outdated technology which is used to monitor the physical changes in environment and take necessary actions. The advancement in WSN leads to automation in physical environment by uploading the sensed data to internet or cloud. Internet of Things is not actually new it's been around for quite some time back in 2010. For example, printer that was connected to the computer over a Wi-Fi, media player connected to the headset over Bluetooth and there were other gadgets that were essentially connected to either mobile phones or to other devices. Today from smart lighting to smart thermostats, connected cameras to environmental sensors, personal voice assistants to variables there are Internet of Things and connected devices everywhere. A different end centre of this revolution is the web which essentially enabled us to connect these devices to each other through a centralized location and with the ability to acquire data store it, process it, query it and analyze it in the cloud (Taivalsaari et al, 2017;l Yao et al, 2015). So these rails of web and the need for connected devices brought us into the era of Internet of Things.

The concept internet of things deals with the issues of making things connected to the internet as well as in a network of smart devices. IoT application development presents an enormous opportunity to reshape entire industries. According to McKinsey & Co, the merging of the physical and digital worlds via IoT could generate up to $11.1 trillion a year in economic value by 2025. Hence, the development of the web based IoT applications will take automation research into next level. Many authors have proposed many solutions to make Internet of Things possible in day today life. This chapter gives the introduction about the web based application development based on internet of things. The major objective of this chapter is to discuss and resolve the challenges in IoT to automate the real time problems.
