An Exhaustive Approach of Application Layer Protocols in IoT

The Internet of Things (IoT) is primarily based on Wi-Fi community connecting a massive range of Smart products and people. It is also known an Internet of Things (IoT). Lightweight IoT gadgets ship greater and realistic facts in the regions of Health Care, Smart Car, Smart Building, Smart Retail, Smart City, Smart house, Industrial IoT (IIoT), etc. The IoT protocols are specifically needed to improve the security of demand. In this paper, an analysis of the application layer and protocols such as CoAP, MQTT, SMQTT, XML, HTTP and Restful is performed. These protocols are used to transfer files from the client to the server. An introduction and evaluation of various application layer protocols are performed at conceptual level involving protection with the message version and messaging capability.
