An Improved Routing Approach for Enhancing QoS Performance for D2D Communication in B5G Networks
Round 1
Reviewer 1 Report
The paper presents a very actual problem regarding the D2D communication in 5G generation networks used in IoT. Of course in ideal conditions everything is theoretically perfect, but in real life, one has to deal with various technical problems and limitations. The authors of this work consider aspects like mobility, battery, link quality, 15 and contention window size-aware routing approach to improve the network performances. The simulations show the advantages of the present decision method in respect to the classic ones used before and presented in the documentation. A goos idea is to clearly describe in lines 68-81 the personal contribution to the work and showing that previously there was no no study reporting multiple device metrics into a single metric for the optimal path selection mechanism.
The references are well studied and properly cited, highlighting the existing problems in such networks and also the solutions for them.
In my opinion, all the calculus and metrics sustain the presented theory. Maybe equations (8),(10), (11) , the figures and a cropped Table1 could be centered to the text, not to the page?
I didn’t notice to be specified in what environment the simulations were done? Maybe that information would be useful.
Overall a thorough and serious work.

Reviewer 2 Report
This paper presents a mobility, battery, link quality, and contention window size-aware routing (MBLCR) approach to boost the overall network performance. I have the following concerns:
1. This work has the same objective as the ref [19]. For both papers, the first author is the same. If ref [19] fulfills the research objective, what is the importance of this study?
[19] V. Tilwari, K. Dimyati, M. H. D. Hindia, M. N. Izam, T. F. B. Tengku, and I. S. Amiri, "EMBLR: A High-Performance Optimal Routing Approach for D2D Communications in Large-scale IoT 5G Network," Symmetry, vol. 12, no. 3, p. 438, 2020.
2. A comparative analysis of both works should be given.
3. In this work, four parameters: mobility, battery, link quality, and contention window size are considered. In [19], four parameters: energy, mobility, queue length, and link quality are considered. Mobility and link quality are common for both studies. How do other parameters affect the performance? Are there any other parameters that we should consider?
4. Some equations are the same such as eq. (1) – (3). Even MCDM is the same which is eq. (11).
5. Results seem to be the same such as Figure 5 of [19] and Figure 4 of this paper presents the same result. In [19], you used EMBLR name, and here MBLCR. Same thing for other simulation results. Justification is needed.

Round 2
Reviewer 2 Report
This paper presents a mobility, battery, link quality, and contention window size-aware routing (MBLCR) approach to boost the overall network performance. I have the following concerns:
1. The 5G network utilizes the mmWave radio frequency range for data transmission, thereby, the signal transmission range is limited to only a few hundred meters [i]. In this case, D2D communication is the prevalent emerging technology that extends the network coverage and seamless connectivity for peer-to-peer users in the 5G network. Therefore, this work has importance but this work has the same objective as the ref [19]. Please provide a comparative study of both works and explain novelty in comparison with ref [19] in Section 1 (Introduction).

2. Please add in each simulation result a comparison with EMBLR [19]. In each result, now there are 3 plots: MP-OLSRv2, MEQSA-OLSRv2, and MBLCR. Please add also EMBLR. Therefore, there should be 4 plots for each simulation result: MP-OLSRv2, MEQSA-OLSRv2, EMBLR, and MBLCR so that we can understand the difference well.
3. Figure 4 is used for two figures. Figure 4. Flow chart of optimal path selection procedure of the MBLCR approach and Figure 4. Throughput with variant devices speed. Please correct it and proofread the manuscript.
