All reviews of published articles are made public. This includes manuscript files, peer review comments, author rebuttals and revised materials. Note: This was optional for articles submitted before 13 February 2023.
Peer reviewers are encouraged (but not required) to provide their names to the authors when submitting their peer review. If they agree to provide their name, then their personal profile page will reflect a public acknowledgment that they performed a review (even if the article is rejected). If the article is accepted, then reviewers who provided their name will be associated with the article itself.
The reviewers' comments have been addressed. I recommend it for publication.
A minor revision is needed before further consideration. I look forward to receiving your revised version.
[# PeerJ Staff Note: Please ensure that all review comments are addressed in a rebuttal letter and any edits or clarifications mentioned in the letter are also inserted into the revised manuscript where appropriate. It is a common mistake to address reviewer questions in the rebuttal letter but not in the revised manuscript. If a reviewer raised a question then your readers will probably have the same question so you should ensure that the manuscript can stand alone without the rebuttal letter.

Thanks for addressing my comments. Here, more justifications are needed for the following two questions:
(1) Why Rayleigh channel, especially when Los link exists. Since LOS links, the Ricean channel will be more suitable instead of Rayleigh. After reading the authors' feedback, I am not still convinced about the use of the Rayleigh channel.
(2) Instead of only text, could the authors provide some simulation results for the baseline strategy.
(3) Please insert the table of all parameters somewhere in the paper instead of listing it only in the response letter.
The paper is not ready for publication. A revision is needed to fix some issues. Please provide a detailed point-to-point response letter along with the revision. Thanks.

The paper studies the optimal power allocation strategy in wireless networks where the energy-constrained relay nodes through RF energy from the UAVs. The addressed problem is interesting and the proposed solution seems effective. However, there are some weaknesses in the paper that the authors must particularly pay attention and handle:
(1) (Line 461 on page 15) The format of references is inconsistent, for example, the caption case of a reference article is inconsistent.
(2) The logic and English usage of this paper are poor. The quality of written English should be improved.
The paper refers to the need to find a suitable α to make a compromise between the outage probability and the throughout, is it necessary to give the appropriate α in the form of simulation?
no comment
(1) (Line 2 on page 1) "UAV cooperative wireless DF relay network." What is DF?
(2) The expression of the formula in this paper is wrong, and the physical meaning of some letters is unclear.
(3) (Line 224 on page 7 and line 242 on page 8) Why the second level headings B and C are the same?

1. In the system model, why choose DF protocol instead of AF protocol? Any justification.
2. Why Rayleigh channel, especially when Los link exists.
3. UAV itself has very limited energy, so it will very impractical to use it as an energy source to power the relay node. The authors must provide substantial evidence to show the effectiveness.
4. What are the computation complexity of solutions used to solve the identified optimization problems?
5. Please provide more baseline strategies used for baselines in simulation.
6. Presentation:
(1) Undefined abbreviation in abstract "DF"
(2) Too many typos and grammar problems.
(3) Please put the figures at appropriate places instead of at the end of the manuscript.
(4) Provide a table to include all parameters to better help the reviewer understand.
