IoT: An Objective Analysis of Architecture, Challenges and Performance Comparison of Various Application Layer Protocols

IoT has made a significant development in recent years. Few years ago, capitalist’s do not take interest to invest in development of this field due to various challenges, however, last decade witnessed increasing demand of IoT devices, investors started taking interest in development of IOT and a major development can be been seen in this domain. With the diversified application areas, IoT covers a large number of devices and every device have their own working limitations. Varying number of devices have their interoperable and configuration issues along with non-consistent architecture and protocols. The aim of this paper is to discuss architecture, overlooked challenges and application layer protocols. Application layer protocol is responsible for conclusive delivery of data to end user through various protocols and the protocol will came in effect, depends upon the device it is working for. Later, a comparative study of various performance variables of protocols has been shown.
