From Radio to In-Pipe Acoustic Communication for Smart Water Networks in Urban Environments: Design Challenges and Future Trends

Round 1

Reviewer 1 Report

This paper provide a comprehensive of the design and analysis for SmartWater Grids (SWGs). In general, this is a piece of interesting works and includes clear surveys. However, some issues should be clarified before confirming a final acceptance.

 

1. Although the authors mention the BER performance of the system, but no simulation result are provided.

 

2. They surveys a variety of modulation schemes, such as BPSK, BFSK and OOK, but lacks the spread spectrum modulation.

 

3. Which typs of encoding and decoding algorithms are adopted in this paper in Fig. 7, Please elaborate.

 

4. As is well known, error correction codes and digital modulations are of great importance to gurantee the BER performance and throughput of the considered communication systems, but they are almostly ignored in this paper.

 

5. More important, the LDPC codes and chaos-based spread spectrum modulation draw a significant amount of interests in the communication field because of their are able to improve the system BER performance and throughput. Pls properly mentioned the following literature [1-4]

Pls make a careful proofread of the paper again.

Reviewer 2 Report

1. In this paper, the paradigm of Smart Water Grids (SWGs) aims at a constant monitoring through a network of smart nodes deployed over the water distribution infrastructure. In such a way, a continuous assessment of water quality and state of health of the pipeline infrastructure can be achieved, allowing an early detection of leaks and water contamination.

2. Please elaborate the technique efficacy of the proposed method in detail.

3. In the figure 3, time between two data transmissions from a remote monitoring unit to the central one/gateway, should be elaborated in detail.

4.In the figure 8, cylindrical coordinate system used for the circular cross section duct, should be elaborated in detail.

5.Please thoroughly revise the language before your submission.

 

Minor editing of English language required.
