Study on IoT Architecture, Application Protocol and Energy needs

In this digital world Internet of Things plays major role in different fields. These IoT devices are extended from Wireless Sensor Network (WSN). This paper we discussed three areas of IoT the architecture, protocols and their energy requirements. Because energy is very most emerging part of IoT devices. Architecture of IoT is very complex one it provides most of the services over the Internet. As far as the application protocols have vital role in end-user level. The IoT device energy efficiency of the nodes is a key factor in the network performance and increasing the life time. In this paper, we discuss the architecture and protocols energy importance for IoT. In this paper we focused IoT application layer comparative study of existing protocols and highlighted some standard IoT application protocol, importance of energy requirements in IoT and existing algorithms are what proposed in some researcher aspects for consuming the energy. This paper focus on analyze the IoT application architecture based lifetime of IoT devices energy management or consuming is future trends in most research challenges that lie ahead. Finally, we provide our conclusion about IoT application layer architecture based on the study that we have conducted.
