Joint Resource Allocation in a Two-Way Relaying Simultaneous Wireless Information and Power Transfer System

Round 1

Reviewer 1 Report

In this paper, authors proposed  joint optimization algorithm to improve resource allocation in Two-way Relaying Simultaneous Wireless Information and Power Transfer System. Although the article deals with a topical subject, it is nevertheless important to improve it. here are my remarks for you:

1. The abstract is too poor and does not reflect the contribution of the article as you have done in the introduction. moreover, the abstract should contain the results obtained.

2. the state of the art in the introduction is not well described. i recommend that you divide the introduction into three parts, i.e. a part on the state of the art containing your motivations, a sub-section on realted works where you treat the articles in the literature as well as their limits. at the end a sub-section on your contributions.

3. A table of comparison between your work and the important articles is necessary.  

4. Another table describing the parameters of your equtions is mandatory for a better reading of the article.

5. The constraints in equations 14, 15 and 16 must be well-defined and explained.

6. how did you get the formula for equation 18 ?. can you do an expansion or add a reference ?

7. please add a pseudo code of your algorithm 

8. the probability of interruption? you mean the outage probability . if so, please change

9. when you derive the outage probability, the SINR is not defined as an equation. please add the SINR formula. in addition the SINR threshold value should be add in the simulation parameters table.

10. you say that the system can select the best relay node differently each time. how is this selection done. please give more details. what is the impact of this selection on the outage probability.

11. as the energy storage threshold increases, the power splitting factor decreases. please explain the result

12. I find that other references are needed to improve your articles please add the suggested:

Reviewer 2 Report

The manuscript is related to simultaneous wireless information and power transfer (SWIPT) technology especially for two-way multi relay communication system considering energy storage model. The manuscript is well structured and shows the ideal well. The detail comments are below.

 1.      In page 9, how does the system notify that the best relay is selected or not during the operation?

2.      In the system view, how can the variables used in the proposed algorithm be obtained without the delay?

3.      In figure 12, how does the definition of system equivalent profit calculated?

4.      It looks like the manuscript needs the discussion section to show the pros and cons of proposed algorithms compared to conventional algorithms.
