Reviewer 1 Report
This is a review paper on the Internet of Things. The author introduced IoT classification, smart IoT architecture, smart software-defined IoT, evolution of IoT architecture, and IoT simulators. However, there are the following problems.
- The author introduced a lot of content, but it was too straightforward and ignored the connection between the works. In other words, the author did not provide a reasonable summary of the various stages of IoT development.
- The summaries in some research areas were not very sufficient, such as “environmental IoT”, “application layer”.
- In the motivation section, the author mentioned a missing link in terms of the evolution of the IoT architectures starting from primitive and traditional frameworks to highly evolved software-defined and virtualized platforms. However, the paper did not elaborate on how to solve this problem.
- The paper lacked prospects for the future and did not point out future research points.

Reviewer 2 Report
This work discusses the conventional IoT networks and the need for Software-Defined Networking (SDN) and Network Function Virtualization (NFV), followed by an analysis of the SDN and NFV solutions to implement IoT in various possible ways.
This study is very interesting but not completely technically sound. The section about IoT Classification and Applications needs to be improved. In particular, the authors should extend section 2.2, a crucial aspect of IoT scenarios.
The paper is well organized.

Reviewer 3 Report
Thank you for inviting me to review this work. It was a pleasure to read and try to understand the message of the authors and the scientific contribution of this work. The article provides comprehensively the concepts of traditional IoT, its drawbacks, and how they can be addressed using SDN-based smart IoT networks. Applications and challenges of IoT are discussed along with the architecture of traditional IoT, leading to the motivation behind SDN-based IoT with disruptive technologies such as NFV, fog computing, and blockchain, etc. The paper is more a state of the art review, however a very interesting and thorough one, making it an important contribution for future research in the addressed field.
