Conflict Detection and Resolution in IoT Systems: A Survey
Round 1
Reviewer 1 Report
In this paper, the authors review conflict detection and resolution in IoT systems. In general, this paper is well written and the topic is interesting. I think this paper deserves to be published after the following revisions:
1 Please elaborate on how conflict detection and resolution link with IoT systems.
2 The challenges faced and future opportunities for research directions should be further highlighted.
3 The Conclusions might be improved with a more in-depth and wide analysis. As far as a review paper is concerned, the authors should clearly point out the current problems and future directions in this field.
4 In order to understand the state-of-the-art in this field in a better way, authors are recommended to include and review the following recent studies to improve the review: [doi.org/10.1109/ACCESS.2018.2879488], [doi.org/10.1109/ACCESS.2019.2939055], [doi.org/10.1109/ICWS53863.2021.00091].
5 All references especially the titles should be in a uniform format. Please double-check it.
6 The full names of the abbreviations such as “HVAC”, “IOT”, and “SQL” should be given when they first appear.

Reviewer 2 Report
This manuscript surveys the topic of conflict detection and resolution in IoT systems. As such, it presents an overview of many publications in the area, and proposes a classification of conflict types, conflict detection methods and conflict analysis and resolution types. The paper is generally well written, readable and understandable, and has very few problems with the English language. The authors survey close to 100 references, therefore the review is thorough and complete. There are some comments that the authors would do well to address:
1. The Abstract is to vague and does not communicate well the content of the paper. Specifically, authors could briefly explain or define what a conflict is and what is the potential gravity of having conflicts (i.e. why researching this topic is important).
2. In the introduction, authors should clarify if there are no other previous publications reviewing the same topic. For example, a quick search on the Internet throwed the following result:
Ibrhim H, Hassan H, Nabil E. A conflicts' classification for IoT-based services: a comparative survey. PeerJ Comput Sci. 2021;7:e480. Published 2021 Apr 27. doi:10.7717/peerj-cs.480
When compared with this reference (and others that could possibly exist), Is this work a completely new survey? Are there overlapping elements with previous reviews? What is novel in this work, or is this survey done with a different specific perspective than previously published ones?
3. The last sentence in Line 148 is incomplete.
4. Conclusions could better summarize the manuscript mentioning where the state-of-the art works are, what is still missing and recapitulate the author's suggestions for future work.
