Reviewer 2 Report

1.     Line 13, 90,334, etc. please put the appropriate symbol × instead of * 

2.     Introduction part is weak and short.

3.     The authors have to mention their contribution in the introduction section.

4.     The readers are also interested in finding how your work is similar and different from the existing work. Hence the manuscript needs to be revised, keeping this in mind. Try to add details about the similar existing work, which I find is lacking in the manuscript. 

5.     The author needs to explain the algorithmic complexity of their proposed Energy Intensity Adaptive Management Algorithm.

6.      Give the limitations and assumptions of your work.

 

7.      The conclusion part is concise. Try to quantify the result in the conclusion section and add future directions of your proposed work for the new researchers.

Some moderate changes required.

Reviewer 3 Report

This paper demonstrated a novel design, integration and application of RF -EH WSN. In addition, the author also introduced an energy management algorithm that can adaptively adjusts the system operating mode and maximize energy efficiency. 

This paper is well written, and their approach is sound.

Thank you very much for taking the time to review this manuscript. 

Reviewer 4 Report

*The number of literature references should be increased and references should be analysed in detail. 

*Table 2 shows the energy conversion efficiencies of the references compared. Conversion cycle times should also be given.

*The maximum self-power distance has been increased from 2.3m to 13.4m according to the references given. The reason for this should be given in detail in the discussion section. 

*In addition, the causes of energy conversion losses should also be explained.
