How to Start 3D Underwater WSN Projects Using OMNET++

To start a 3D Underwater Wireless Sensor Network (UWSN) project in OMNeT++ which needs to have numerous steps to configure the simulation environment, describing underwater-specific properties, and executing the required protocols. Below is a sequential technique to get started:

Steps to Start 3D Underwater WSN Projects in OMNET++

  1. Understand the Basics

Initially, we need to understand the core concepts:

  • 3D Underwater WSN (UWSN): We should know the characteristics of 3D UWSN, challenges like propagation delay, limited bandwidth, and energy constraints, and its uses like environmental monitoring, surveillance.
  • OMNeT++ Framework: Focus on the OMNeT++ basics and their components, NED files, INI files, and C++ scripting.
  • AquaSim or Underwater Framework: Delve into underwater-specific frameworks such as AquaSim-ng that prolong the OMNeT++ for underwater networks.
  1. Set Up the Environment
  • Install OMNeT++:
    • Go to official OMNeT++ webpage to download and it on the system.
    • Then, configure the essential environment variables.
  • Install an Underwater Framework:
    • We require downloading AquaSim-ng or other underwater network simulation modules that are compatible with OMNeT++ environment.
    • Get the offered guide to compile the framework.
  1. Define the 3D UWSN Simulation Scenario
  • Network Topology:
    • We should delineate the number and kinds of sensor nodes such as stationary or mobile nodes like Autonomous Underwater Vehicles (AUVs).
    • Deliberate the3D distribution of nodes as well as depth.
  • Environment Parameters:
    • Set properties of water such as attenuation, salinity, and temperature that impact the acoustic signal propagation.
  • Protocol Selection:
    • Decide on interaction protocols for underwater communication like:
      • MAC Protocols: These protocols support T-Lohi, S-FAMA, or Aloha-based protocols.
      • Routing Protocols: It used in VBF (Vector-Based Forwarding), HH-VBF, or Depth-Based Routing.
  1. Create the Simulation Project
  • Set Up a New Project:
    • In IDE, we want to make a new OMNeT++ project.
    • It contains the underwater framework like AquaSim-ng within the project settings.
  • Design the 3D Network Topology:
    • Model the underwater topology exploiting .ned files including nodes that are delivered in 3D space.

Example NED File:

network Underwater3DNetwork

{

submodules:

node[10]: UnderwaterNode;

sink: UnderwaterSink;

connections allowunconnected:

node[*].nic <–> sink.nic; // Connect nodes to the sink

}

  1. Configure Simulation Parameters
  • Edit the INI File:
    • Indicate environmental and protocol parameters to alter the INI file.

Example INI Configuration:

[General]

network = Underwater3DNetwork

# Simulation parameters

sim-time-limit = 100s

*.node[*].mobilityType = “BubblesMobility”

*.node[*].communicationRange = 200m

*.node[*].depth = uniform(10, 100)  # Node depths

*.sink.position = “0,0,0”           # Sink at the surface

*.node[*].mac.protocol = “T-Lohi”  # MAC protocol

*.node[*].routing.protocol = “VBF” # Routing protocol

  1. Develop Custom Modules (Optional)
  • Node Behavior:
    • We would inscribe custom C++ modules delineating the underwater nodes’ behavior with mobility and sensing.
  • Channel Model:
    • Execute the underwater acoustic channel properties like delay, attenuation, and noise for channel model.
  • Energy Model:
    • We describe an energy consumption models designed for sensing, transmission, and reception.
  1. Run the Simulation
  • In OMNeT++ IDE, we compile and run the simulation.
  • Then, monitor the simulation within the runtime environment, confirming network behavior and 3D topology.
  1. Analyze Results
  • Transfer information or make use of OMNeT++ analysis tools for external analysis.
  • We want to assess the performance indicators such as:
    • Packet delivery ratio.
    • End-to-end delay.
    • Energy consumption.
    • Network lifetime
  1. Iterate and Optimize
  • Change simulation metrics such as node density, protocols, or environment properties to experiment the diverse scenarios.
  • Enhance the protocols for better performance in underwater limitations.
  1. Document Your Findings
  • Make a report or research paper to define:
    • Simulation goals and configuration.
    • Protocols and sets up.
    • Outcomes and analysis.
