1. INTRODUCTION

Along with the explosive growth of internet, cloud computing, modern wireless telecommunication and big data and rapid increase in its economics, daily life intelligence demand has become higher level. By providing anytime, anywhere connectivity with anyone, internet has got closer to the human life. Now the world internet is expanded as Internet of things (IoT).

Things can be also called as objects. They may be virtual or may be real. When they are communicating each other it is called as things-to-things communication. In the area of IoT these “things” also have the ability of communicating with the people. It will be called as things-to-human communication.

In the technological term, SMART stands for Self-Monitoring, Analysis and Reporting Technology. What smart really does is to take some input from external and apply ‘brainpower’ of it and take some actions.

When the uniquely identifiable objects (things) connect to the internet via standard protocols in specific infrastructure then that whole system is said to be “Internet of Things” (IoT). The “things” are connected to a common network path with the aim of communicating, exchanging data and information, and control others. The whole system will be interconnected with an embedded software, hardware and sensors.

IoT consists of three layers such as perception layer, network layer and application layer respectively. The responsibility of data collection in IoT is accepted by the Perception Layer. It consists of all kind of sensors such as humidity sensors, temperature sensors, cameras, GPS, RFID tags and related readers. Network Layer acts as a media. It collects data from the perception layer and processes them for application layer. It consists of all kind of networks such as internet, broadcast network, 2G and 3G communication network. Application Layer is the place where the user and IoT meet each other. It can be called as the interface
