Basic reporting

The authors have addressed most of the previously raised issues. However, a few concerns still need to be addressed, as outlined below:
1. The Abstract section is overly long; I recommend condensing it to improve clarity and focus.
2. Figure captions should be placed below the figures, not above them, in accordance with standard formatting guidelines.
3. Please improve the resolution of Figure 1 to ensure better clarity and readability.
4. I still recommend removing Figures 4 and 5, as they are more suited to a technical report rather than a research article.
5. Figure 15 lacks clarity; I suggest using alternative visualization methods to present the results more effectively.

Experimental design

I recommend to include more details about the experiment testbed.

Validity of the findings

I recommend to include more discussions.

Basic reporting

Authors have addressed most of the existing issues, however, there are several issues need to be considered as follows:
1. I recommend to remove the title "Problem Definition and Motivation" and add the two paragraph to the Introduction Section.
2. The Second Paragraph in "Related Works Section" is a very long paragraph. I recommend to divide this paragraph into shorten paragraphs.
3. I recommend to remove Figure 3. This is not a graduation project.
4. Figure 16 is totally unclear.
5. I recommend to address the following relevant research papers:
a. Social distance monitoring approach using wearable smart tags
b. A hybrid range-free localization algorithm for zigbee wireless sensor networks
c. A SLAM-based localization and navigation system for social robots: The pepper robot case

**PeerJ Staff Note:** It is PeerJ policy that additional references suggested during the peer-review process should only be included if the authors agree that they are relevant and useful.

Experimental design

I recommend to reconsider Figure 3, 4, 5, 6, and 16.

Validity of the findings

Authors have addresses the raised issues in the Results Section.

Basic reporting

1. Problem Statement and Motivation: The rewritten introduction clearly outlines the research gap.
2. Literature Review: The related works section has been updated with more recent references.
3. Methodology: The suggested system is now well-defined.
4. Experimental Design and Results: Additional assessment metrics, statistical analysis, and explanation increase the credibility of the findings.
5. Figures and Presentation: Figures have been made more intelligible.
6. Language and Clarity: Some sentences might be improved for greater readability. A last proofreading pass is recommended.
7. Figure Formatting: Although enhanced, the figures may still be optimised for greater visual clarity.
8. Referencing Consistency: Ensure that all citations are uniformly structured.

Basic reporting

This paper proposed an improved algorithm combining a refinement procedure with PSO, called as DVHOP-PSO. This area is considered as a hot research area, however, I believe that this paper requires major revision prior to be accepted for publications.
Authors used poor English to illustrate the work presented in this paper.
The Introduction Section does not contain the problem neither the motivation for proposing this approach. Therefore, I recommend to rewrite the Introduction Section.
Authors didn't provide sufficient relevant studies in the Related Works Section. I recommend to rewrite this section, while considering several recent research works, and discuss the results of the existing works.

Experimental design

In this paper, the experimental design and implementation requires to be reconsidered.
For instance, authors included a section named as "Proposed Methodology", I recommend to change this title to Proposed system for example.
Authors didn't provide enough information about the proposed system, where authors offered only very basic details. I recommend to discuss your work in more details.
I recommend to reconsider the whole section "Proposed Methodology".

Validity of the findings

The obtained results are reasonable, however, I recommend to include a set of evaluation metrics that have been considered to assess the efficiency of the developed system.
Moreover, authors need to add more details with regards to the results section, and include more analysis and discussions.

Additional comments

In conclusion, the presented work in this paper is not acceptable for publication in its present format.
I recommend to rewrite the whole paper in a format of research paper.

Reviewer 2 ·

Basic reporting

The English in this manuscript can be improvised.

The literature references are quite simple and not too recent. I think they can be improved. Insufficient background/context provided.

The paragraphing is poor and needs modification.

The results presented can be improved as it is only presented in graph form which is quite difficult to grasp.

Need to improve on results discussion. Some statistical analysis will be helpful.

The improvement in PSO is quite shallow. The authors should show and justify the modification they are proposing.

The figures are poorly presented.

Experimental design

Perhaps there is some contribution but I failed to see it. Probably they have to highlight the contribution.

Quite hard to identify the knowledge gap.

No rigorous investigation was performed. Many elements of evaluations are not addressed. Perhaps they need to show the standard evaluations/assessments done for similar applications.

The proposed method was not described comprehensively and in detail.

Validity of the findings

None of the requests of publisher are properly address.
