Internet of things: A comparative study

Abstract

Internet of Things (IoT) is the field that connects things together and to the Internet, letting them exchange data, communicate with each other and interact with the human. Recently, it has been widely used to go beyond the machine to machine (M2M) communication and covers variety of protocols and applications that facilitates people's way of living. However, many challenges still hinder its advances, especially security and power issues. In this paper, a comparative study for IoT architectures, platforms and applications is presented with a case study to illustrate the main IoT concepts and levels of abstraction. Then, a Strengths - Weaknesses - Opportunities - Threats (SWOT) analysis is presented to assess the present and the future of IoT.
