5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Authors proposed optimizing energy consumption based on stochastic geometry with QoS framework. Here are some comments:

1- In abstract, the value achieved in improving energy consumption and its difference from the most efficient method must be mentioned.

2- In abstract, the research methodology is not well articulated and is somewhat messy.

3- In the introduction, Figure 1 does not clearly list the purpose of its existence in terms of energy efficiency over the recent years.

4- In line 70, the fundamental challenges are not mentioned

5- In the line 83, it is better to delete a (random)

6- In line 99, what are the three approaches, it should be listed and explain what it is HetNets in line 100.

7- In related works, due to the importance of both DAS and LAS, its working mechanism must be explained.

8- It is preferable to divide the related work according to common mechanisms.

9- The “Related Work” and “Introduction” sections lack of enough references. I strongly recommend that the author improve this section by adding references that support all the claims, the challenges of QoS, and motivation of the problem. The author may precisely and comprehensively point out the current issues and existing solutions. I suggest adding more related reference such as:

https://ieeexplore.ieee.org/abstract/document/9799997

https://link.springer.com/chapter/10.1007/978-981-19-1653-3_9

https://link.springer.com/chapter/10.1007/978-3-031-19523-5_6

https://ieeexplore.ieee.org/abstract/document/9768338

https://link.springer.com/chapter/10.1007/978-3-030-95987-6_1

10-In line 169, please replace oversimplified � simplified

11- In lines 174-175, “EE algorithms based on sleep mode strategies, the negative impact on QoS (174 when BSs are turned 175 into sleep mode) has been ignored in various research the publications”, What is the proof for this claim?

12-Contributions are worded superficially and do not fit with the proposed work. They must be explained in depth

13- Section 6 . Mathematical Preliminaries, Lacks references

14- The role of stochastic geometry in the work is not entirely clear

15- In line 237, “that the density of the points will remains constant throughout the Euclidean space.”, the constant of these points may affect accuracy

16- In section 7. System model, There is a bit of ambiguity and messy as to whether the proposed work is two-tier or multi-tier

17-In line 267, these conditions were not mentioned or clarified

18- In lines 284-285, this wake-up time requires clarification

19- Table 3, how were these values assigned?

20- In lin2 309, the percentages are 67% and 98%, how were they obtained, and the context of the work is here

21- The variables and factors of Equation 13 and 16 are not explained

22- In line 22, the transmission power was assumed to be constant, which may affect the validity of the results of the proposed work

23- The algorithms are good in terms of formulation, but require more clarification to explain the role of each one

were these values established?

Reviewer #2: 1- It is possible to add references to Table 1 according to the mentioned distribution

2- The research papers in Related Work are not arranged according to year of publication (from oldest to newest). In addition to the possibility of mentioning the failures of each research.

3- It is possible to discuss the results and build clear and scientific conclusions, in addition to setting a future outlook for researchers in this field

4-Standardize the format of references
