PeCO is better? Maybe include computation time or something that is as convincing as the energy

+\textcolor{green}{\textbf{\textsc{Answer:} In fact, we included a new performance metric that linked to the energy, called Energy Saving Ratio (ESR). We added new section in the result part related to this performance metric that shows our PeCO protocol provides better energy saving compared with other approaches.}}\\

"DiLCO outperforms PeCO when the coverage ratio is required to be $>90\%$, but PeCo extends the network lifetime significantly when coverage ratio can be relaxed." Also, can you add applications where
you would want to have a coverage ratio of $50\%$? This seems like a very small ratio and as you
increase it, DiLCO becomes the methodology that has the maximum network lifetime. If you don't
include application examples, your statement "Indeed there are applications that do not require a
100$\%$ coverage of the area to be monitored." stronger. }}

+\textcolor{green}{\textbf{\textsc{Answer:} Thank you so much to your suggestion for adjusting the sentence in the end of Section 5.2.5. (previously Section 5.2.4.), It is done.
+For the applications, we added some applications examples in the end of the sentence "Indeed there are applications that do not require a 100$\%$ coverage of the area to be monitored." as well as we changed the figure 10 (previously figure 9) by adding DilCO/70 and PecO/70 instead of DilCO/50 and PeCO/50 }}\\
