# Underwater Wireless Sensor Network Performance Analysis Using Diverse Routing Protocols
## 3 Network Scenario  
The QualNet program is a simulator that can emulate the behavior of a network. A network can be established in an atmosphere free of risk and expense by employing the use of a simulation. The network design tool that comes with the QualNet 7.1 simulator provides users with an intuitive interface for the purpose of configuring simulation settings and generating network scenarios. Building a network architecture using a drag-and-drop interface is now a simple and rapid process. Reviewing the statistical data that was created by the QualNet network simulator is accomplished through the usage of its Analyzer graphic user interface. A statistics file with the extension. The stat is generated whenever a simulator is started from inside of Architect. The findings of the simulation are presented in this document. Because it is stored in text format, the basic statistics file can be accessed by using any text editor that supports text. Graphs such as this one could be constructed with the use of statistical data [33; 34].
* The scenario planning phase involves building a model of the network via a random waypoint model;
* In the second stage, data is collected from the source node to the destination node using various traffic load applications, such as CBR, VBR, and FTP;
* The third step is to put in place routing protocols and run simulations of potential network configurations;
* In the fourth place, we have a comparison of the results of various assessments of the performance of ad hoc routing systems;
* Analysis and interpretation of results constitute the final step.  
Considering the constant bit rate (CBR) as a deployment application, there are accessible existing networks available. In the proposed network, file transfer protocol (FTP) and variable bitrate (VBR) are considered alongside CBR, and the parameters for all three FTP, CBR, and VBR applications are then compared [35; 36]. The proposed scenario has a 1500 \(\times\) 1500 square meter design in the Qualnet 7.1 Simulator. The FTP, CBR, and VBR applications are connected between 60 and 120 nodes, of which 15 are node devices, 25 are ship devices, 20 are sensor devices for 60 nodes, 30 are node devices, 50 are ship devices and 40 are sensor devices. The simulation lasts for 500 s in total. Random waypoint mobility with a minimum speed of 1.5 m/s and a maximum speed from 3 to 10 m/s is the node mobility model that has been selected. Beyond AODV, the other considered routing protocols are DSR, DYMO, LAR1, Bellman-Ford, OLSR, Fisheye, STAR-ORA, ZRP, and STAR-LORA. After finishing the test, the graphs in the simulator were considered. The required performance metrics are thus obtained, including the average transmission delay, average jitter, percentage of utilization, and the energy used in transmit and receive modes. The proposed underwater wireless communication scenario with multiple nodes in X-Y and 3D visualization is shown in Figures 4 and 5 for 60 nodes. Runtime proposed scenario for underwater wireless communication with various nodes in both X-Y and 3D visualization is shown in Figures 6 and 7 for 120 nodes [37; 38].
