How to Start LiFi Projects Using OMNeT++

To start a LiFi (Light Fidelity) project in OMNeT++ that has includes replicating the optical wireless interaction systems. LiFi that frequently utilizes for light to send information that can be designed for diverse places like indoor networking, vehicular communication, and hybrid LiFi/WiFi networks. Below is a comprehensive method to get started:

Steps to Start LiFi Projects in OMNeT++

  1. Understand LiFi Concepts
  • LiFi Basics:
    • Make use of the visible light spectrum, data is sent through light-emitting diodes (LEDs).
    • Interaction has to rely on line-of-sight or reflected light.
  • Key advantages:
    • High data rates.
    • Reduced interference.
    • Energy-efficient (LEDs as dual-purpose lighting and communication).
  • Applications:
    • It is often utilised in indoor networking, IoT, vehicular communication, hybrid WiFi-LiFi systems.
  1. Set Up OMNeT++ Environment
  • Install OMNeT++:
    • We should download the new version of OMNeT++ environment from its official website.
  • Install INET Framework:
    • We have to include the framework as it offers essential networking protocol support and is the starting point for executing the LiFi.
  • Custom Framework:
    • While OMNeT++ doesn’t have built-in LiFi support, we must make or prolong the modules replicating the optical interaction.
  1. Define Project Objectives
  • Decide on a focus objectives of this project:
    • For instance, we may choose: “Performance evaluation of LiFi networks in an indoor office environment.”
  • Define measurable goals:
    • We need to evaluate the key metrics such as throughput, latency, and signal coverage in various lighting conditions.
    • Likewise, we should equate the LiFi with WiFi or hybrid systems.
  1. Model LiFi Network Components
  • Transmitters (LiFi Access Points):
    • We should make use of LEDs like optical transmitters including the adjustable indicators like wavelength and power.
  • Receivers (Devices):
    • We have to design photodetectors or devices that are furnished with optical receivers to ensure the compatibility.
  • Channel:
    • We should replicate the visible light communication (VLC) channels while deliberating:
      • Line-of-sight.
      • Reflection and diffraction.
      • Ambient light noise.
  • Network Topology:
    • We have to describe the LiFi transmitters and receivers placement within a certain environment.
  1. Implement LiFi-Specific Features
  • Propagation Models:
    • We need to make custom modules for optical signal propagation.
    • To deliberate the features of LiFi like path loss, signal reflection, and interference.
  • Modulation Techniques:
    • We should execute the LiFi-specific modulation schemes such as OFDM (Orthogonal Frequency Division Multiplexing) or OOK (On-Off Keying).
  • Handover Mechanisms:
    • We may model methods to manage handovers among the LiFi access points or between LiFi and WiFi.
  • Hybrid Networks:
    • We must replicate a hybrid LiFi/WiFi system and enhance the algorithms to balance traffic distribution effectively.
  1. Set Simulation Parameters
  • Make use of .ini files to configure settings such as:
    • Network Topology:
      • Define the volume and placement of LiFi transmitters and receivers.
    • Environmental Parameters:
      • It includes room dimensions, reflective surfaces, and ambient light.
    • Traffic Patterns:
      • Describe the traffic patterns like user data traffic and mobility models.
    • Channel Properties:
      • Transmission power, wavelength, and noise levels are channel properties.
  1. Simulate Scenarios
  • We should include scenarios such as:
    • Indoor environments like office, conference rooms, homes.
    • Vehicular communication using LiFi for car-to-car communication.
    • Hybrid WiFi-LiFi systems to make sure seamless connectivity.
  • Metrics to evaluate:
    • We have to estimate the indicators such as throughput, latency, signal coverage, handover efficiency.
  1. Analyze Results
  • Transfer information into external OMNeT++’s built-in tools such as Python or MATLAB for visualization and analysis.
  • We need to equate the performance of LiFi with other technologies like WiFi or 5G.

We had effectively performed simulations for LiFi projects using a stepwise approach within the OMNeT++ environment.
