How to simulate underwater wireless communication projects using network simulation tools?

Simulation of underwater wireless communication projects is examined as an interesting as well as major process. Several guidelines have to be followed to carry out this process in an efficient manner. To build and execute an underwater wireless communication simulation with Aqua-Sim, we provide a procedural instruction explicitly: 

Procedural Instruction to Simulating Underwater Wireless Communication with Aqua-Sim

Initially, you should install NS2, because Aqua-Sim is developed along with NS2. To carry out these processes, consider the following procedures:  

Step 1: Install NS2

• Download NS2:
  • Utilize package managers such as apt for Ubuntu or visit an authorized website for downloading NS2.

sudo apt-get install ns2  

• Check Installation:
  • By executing Ns, assure that the NS2 is installed on your system in an appropriate way.

Step 2: Download Aqua-Sim:

• From the Aqua-Sim GitHub repository, you can download Aqua-Sim.
• It is important to retrieve all the necessary Aqua-Sim files. Then, the installation guidelines that are offered in the repository have to be complied.

Step 3: Install Aqua-Sim:

• Compile the code after directing to the Aqua-Sim directory.

cd Aqua-Sim

make clean

make

2. Develop a Simulation Script

In order to specify the underwater communication setting, develop a TCL script. Consider the following instance of script: 

# Load necessary libraries

source ns-mobilenode.tcl

# Create the simulator

set ns [new Simulator]

# Define options

set val(chan)   Channel/UnderwaterChannel  ;# Channel type

set val(prop)   Propagation/UnderwaterPropagation ;# Propagation model

set val(mac)    Mac/UnderwaterMac   ;# MAC type

set val(ifq)    Queue/DropTail/PriQueue ;# Interface queue type

set val(ll)     LL                   ;# Link layer type

set val(ant)    Antenna/OmniAntenna  ;# Antenna model

set val(x)      1000                 ;# X dimension of the topography

    set udp_($i) [new Agent/UDP]

    $ns attach-agent $node_($i) $udp_($i)

    set null_($i) [new Agent/Null]
