Comparative Study of IoT Protocols

Abstract

Internet of thing, or Connected Objects (IOT) is considering a modern concept. A few years ago, the IoT has invaded our professional and personal life revolutionizing the near future. Indeed, the goal is to create an environment composed of intelligent devices and systems which can communicate with each other through computer networks. These data exchanges allow better decision-making in an increasingly complex context. The success of the Internet depends on the widespread adoption of clearly defined protocols. It represents a common language to all connected systems, regardless of brand, operating system or software tools used. In the absence of such a common language, the Internet would be reduced to a patchwork of proprietary and incompatible networks. This research analyses some of the major evolving and enabling protocols in the IoT. Particularly, it focuses on Layer Network and applications Protocols. Our study evaluates their capabilities and compares their main characteristics and behaviors in terms of various criteria of these protocols. The comparison presented in this paper would benefit researchers and developers in selecting an appropriate protocol for the IoT applications. In This paper we aim to provide first a complete overview of the IoT architecture, then the different protocols. In addition, we present a comparative of application and network layer protocols.
