Reviewer 2 Report
1) At the beginning of the Introduction, the authors provide a nice overview of the main application scenarios of WSNs. However, some of the references are a bit outdated even if the topics covered (e.g., environmental monitoring) significantly expanded over the last two/three years. Therefore, in my opinion it is necessary to replace or extend the literature overview by adding more recent references on the topic, which also more clearly highlight the main technological evolutions of WSNs and how they will play a fundamental role in the coming IoT era. From a quick search on Google schola, some interesting and very recent references that I could suggest are:
- "Toward Integrated Large-Scale Environmental Monitoring Using WSN/UAV/Crowdsensing: A Review of Applications, Signal Processing, and Future Perspectives", Sensors, 2022;
- "Machine Learning for Wireless Sensor Networks Security: An Overview of Challenges and Issues", Sensors, 2022.
2) Please fix the dimensions of Table 1 so that it can fit the space of the template. Currently, it falls beyond the limits. The same for Table II.
3) Please improve the readability of equation 4.
4) The sum symbol in equation 18 is too big. Please resize it.
5) In Sec. 5, I would suggest corroborating the performance results with some computational complexity analyses, so as to better highlight potential trade-offs between performance and cost.

I recommend accepting the paper
Reviewer 2 Report
The authors have correctly addressed all my comments. Just a very small additional comment: Fig. 9 falls beyond the page limits and is currently cut. Please fix it.
