Evaluation and Study of IoT Entrances

Abstract

The people in the present scenario are leading a busy life which is filled with modern technology that changes rapidly. In such a rapid growth of the human race, technological developments were also increasing rapidly. At the beginning of the twenty-first century, technology turned its focus towards automation which leads to the development of new innovative technology called IoT. But it is a bit harder to implement because IoT is not just connecting hardware devices with the Internet, but it is the interconnection of devices with the Internet that should work with intelligence. To do that, we should require gateways and a cloud to store data. The main key element in the complete success of IoT is the gateway. A gateway is a device either a hardware device or a software program that connects the client and the server. The server or the cloud consists of data and this data from the cloud to server and vice versa can be done through these gateways. The functioning of a gateway is not only to relocate the information between the consumer and the server but also to maintain protocols and to ensure security to the continuous flow of data that is exchanged between the client and the server. In the above paper, we gave a complete gist regarding the IoT gateways and explain the working or functionalities of different gateways in different applications.
