Sustainable Power Consumption for Variance-Based Integration Model in Cellular 6G-IoT System
Round 1
Reviewer 1 Report
In this manuscript, the authors propose a variance-based integration model to balance the 6G IoT system performance, power consumption and computational complexity. The whole manuscript is relatively well structured, with the detailed background introduction and related work discussion. However, I have some concerns stated as follows.
1. The authors claimed three contributions at the end of Section 1. But the second contribution seems more like the introduction to the specific solution rather than presenting the novelty of this work.
2. In the last paragraph, the manuscript organization is given in which 7 Sections are briefly introduced. However, there are only 5 Sections shown in the manuscript. Please carefully check that issue.
3. In Algorithm 1, the format is suggested to be improved by using more mathematical elements (e.g., symbols, operators) instead of textual descriptions to make the pseudocode more professional.
4. In Section 4, the definitions of the adopted evaluation metrics such as MSE, MAE, MALE, MAPE are suggested to be added for helping audience better understanding those evaluation metrics.
5. In Section 4, the key settings for the baseline models are expected to be provided. For instance, the architecture and key hyperparameters (e.g., learning rate, batch size) of ANN should be provided so that the experiments could be easily reproduced on that basis.
6. The literature review is expected to be further improved. The authors could refer to the following papers:

Reviewer 2 Report
Provide a clear and concise introduction that sets the context for the paper. The current introduction could be expanded to include a brief overview of the importance and potential impact of 6G networks and IoT techniques, as well as the specific research gap or problem that the paper aims to address.
Clearly define the significant issues of 6G cellular IoT, namely information transmission, data aggregation, and power supply, in a separate section or subsection. This will help readers understand the specific challenges and objectives of the proposed integrating model.
Elaborate on the variance-based integrating model for the 6G IoT approach, explaining the underlying principles and mechanisms in more detail. Provide a clear explanation of how the model considers energy, communication, and computation (ECC) aspects to address the identified issues.
Expand on the methodology used to charge IoT devices concurrently using wireless power transfer (WPT) in the downlink. Provide information on the technical aspects of WPT implementation, such as the power transfer efficiency, frequency, and range considerations.
Discuss the integration of transmit beam optimization through the Improved Ant Colony Optimization (IACO) model in greater depth. Explain how the IACO model is applied to balance system performance, power consumption, and computational complexity. Provide insights into the specific optimization parameters and algorithms utilized.
Provide a more comprehensive analysis and discussion of the simulation outcomes. Present not only the mean squared error (MSE) values but also other relevant performance metrics, such as throughput, latency, or energy efficiency. Compare the proposed model with existing conventional models in terms of multiple performance indicators to demonstrate its superiority more convincingly.
Please avoid citing sources that were published before to 2019. Cite current research that are really pertinent to your topic. The study also lacks sufficient citations. Another critical step is to compare the topic of the article to other relevant recent publications or works in order to widen the research's repercussions beyond the issue. Authors can use and depend on these essential works while addressing the topic of their paper and current issues.

Reviewer 3 Report
In this study, authors proposed a variance-based integrating model for the 6G IoT approach that considers energy, communication, and computation (ECC). Initially, the base station (BS) charges huge IoT devices concurrently utilizing WPT in the downlink. After that, IoT devices gathered the energy to perform the communication task and the computation task in the uplink in a similar spectrum. Also, the model integrates the optimization of transmit beams via the Improved Ant Colony Optimization (IACO) model to balance the system performance, power consumption and computational complexity.
although the article has the merit of being accepted, here are my comments:
1the summary is too long and it is difficult to see the real contribution of the authors.
2-I recommend that you draw up a comparative table between your work and the major reference articles.
3- Your system model is badly introduced and several gaps are recorded.
4-l'éuqtaion 1 necessite d'être référenci
5-The architecture of Figure 1 is not clear, it is recommended to add explanations and to make a visible figure.
6-All your equations are not referenced and take more care when writing your equations.
7- Figure 2 needs a very good explanation in the text.
8-Your results are badly interpreted and your graphs are badly represented, use Python or Matlab to plot your results.
9- Please try to compare your results with others.
