Trust-Degree-Based Secure Relay Selection in SWIPT-Enabled Relay Networks

Round 1

Reviewer 1 Report

The paper titled "Trust-degree-based Secure Relay Selection in SWIPT-enabled Relay Networks" is a promising paper. However, I have some concerns and recommendations for the improvement of the paper. 

1. In the abstract you need to mention how significant the energy consumption reduction is. 

2. The literature review is not provided in the introduction or as a separate section. Overall, the number of references is limited.

3. why did you set the energy conversion efficiency η = 0.99, and the confidential information rate threshold to R = 0.5 Mbps?

3.  Discussion section would be nice if you added it so that we can see what is the differences between the proposed method and the literature.

4. The paper needs justification with experimental values.

Reviewer 2 Report

Although this paper contains a certain level of novelty, the following limitations need to be resolved to be  considered for publication.

First, the proposed scheme needs to be compared to other related work unless it is the first work and thus there are no other work to be compared.

Second, this paper contains many mathematical equations. However, the explanation of implications of these equations is not enough. Authors need to add more explanation regarding these equations.

Dear authors, 

Thank you for addressing my concerns. But I still think there should be an experimental validation for the proposed model. 

Thank you.

Dear authors,

It seems like, I couldn't get answers to most part of my questions. I still have concerns about the experimental validation of your results.

Thank you.
