I. Introduction
The Internet of Things (IoT) is a massive network of interconnected things and people that all gather and exchange data about how they are used and the world around them. Evolution of internet began by connecting computers [1]. Later a number of systems were connected together which resulted as World Wide Web. People started using the internet via social networks [2]. Thus, the idea of connecting daily objects to the internet was proposed, which lead to the development of IoT technology. In IoT there is an involvement of number of objects. These objects possess different shapes and varied sizes for example smart watch, smart tv, smart microwave etc. The data for these smart devices is being captured through varied complex sensors and with the help of these sensors they are able to detect the objects coming in their paths for example wearable smart watches are able to monitor and measure heart rate or number of steps taken by the user. This detailed information is being used to make suggestions and help you to take necessary action [2]–[3].
