How to Implement Optical Visual MIMO in OMNeT++

To implement Optical Visual Multiple Input Multiple Output (MIMO) in OMNeT++ has needs to emulate a communication system where multiple optical transmitters and receivers are used to improve the data transmission rates and reliability. The Optical Visual MIMO is especially associated in Visible Light Communication (VLC) systems in which LED arrays transfer the data and photodiodes receive it. The below is the procedure to implement the approach with these examples:

Steps to Implement Optical Visual MIMO in OMNeT++

  1. Set Up OMNeT++ Environment:
    • Make sure OMNeT++ and the INET framework are installed and configured correctly.
    • To deliberate the expanding the INET or using a particular VLC simulation framework if available.
  2. Design the Optical MIMO System Architecture:
    • Describe a system with multiple optical transmitters like LEDs and receivers like photodiodes or cameras.
    • Generate a network topology that contain these elements, along with any essential intermediate components such as optical amplifiers or relay nodes.
  3. Develop or Extend Optical MIMO Models:
    • Create models for the optical transmitters and receivers, incorporating key MIMO concepts such as spatial diversity and multiplexing.
    • Implement models for the optical channel, taking into account factors such as path loss, noise, and interference between channels.
  4. Configure MIMO Techniques:
    • To execute MIMO techniques such as Spatial Multiplexing, where different data streams are transmitted on separate optical paths.
    • On the other hand execute diversity approaches to enhance the reliability of data reception by integrating the signals received from multiple paths.
  5. Implement Optical Channel Modelling:
    • Describe the features of the optical channel has parameters like line-of-sight (LOS) conditions, beam divergence, and the impact of ambient light.
    • To deliberate to execute a channel model that accounts for reflection and scattering effects specifically in indoor environments.
  6. Simulate and Analyse:
    • Execute the simulations to monitor how the Optical Visual MIMO system performs under diverse conditions, like varying transmitter-receiver distances or interference levels.
    • To gather the parameters such as bit error rate (BER), data throughput, and signal-to-noise ratio (SNR) for analysis.
  7. Visualize and Evaluate Results:
    • To monitor the MIMO communication process that has the interactions among the multiple transmitters and receivers using the OMNeT++’s visualization tools.
    • Measure the outcomes to determine the efficiency of the MIMO techniques in improving communication performance.

Example Configuration

The below is the sample configuration for an Optical Visual MIMO system in OMNeT++:

network = OpticalMIMONetwork

sim-time-limit = 100s

[Config OpticalMIMONetwork]

*.numTransmitters = 4

*.numReceivers = 4

*.transmitter[0].type = “OpticalLED”

*.transmitter[1].type = “OpticalLED”

*.transmitter[2].type = “OpticalLED”

*.transmitter[3].type = “OpticalLED”

*.receiver[0].type = “Photodiode”

*.receiver[1].type = “Photodiode”

*.receiver[2].type = “Photodiode”

*.receiver[3].type = “Photodiode”

# Define the optical channel between transmitters and receivers

connections = [

{ srcNode = “transmitter[0]”, destNode = “receiver[0]”, channelType = “OpticalChannel” },

{ srcNode = “transmitter[1]”, destNode = “receiver[1]”, channelType = “OpticalChannel” },

{ srcNode = “transmitter[2]”, destNode = “receiver[2]”, channelType = “OpticalChannel” },

{ srcNode = “transmitter[3]”, destNode = “receiver[3]”, channelType = “OpticalChannel” }

]

# Define MIMO configuration parameters

*.transmitter[*].wavelength = “650nm”

*.transmitter[*].power = 1.0W

*.receiver[*].sensitivity = -30dBm

*.receiver[*].fieldOfView = 60deg

Example Scenarios

  1. Scenario 1: Spatial Multiplexing

Execute spatial multiplexing in which numerous data streams are transferred instantaneously from numerous LEDs to isolate the photodiodes. To emulate the how this upsurge the information throughput and measure the BER for each channel.

  1. Scenario 2: Diversity Reception

Execute a diversity scheme in which the same information is transferred from multiple LEDs, and the receivers integrate the signals to enhance the reliability. Evaluate the enhancement in SNR and the reduction in BER.

  1. Scenario 3: Impact of Interference

To mimic a scenario where multiple Optical Visual MIMO systems performs in the same space that leading the interference. Measure how the system manages the interference and whether MIMO algorithm can prevent its effects.

Considerations:

  • Channel Modelling: Accurately model the optical channel that deliberate factors such as reflection, scattering, and ambient light and these factors can expressively impact the performance of an Optical Visual MIMO system.
  • MIMO Techniques: Testing with numerous MIMO algorithms like spatial multiplexing vs. diversity to regulate in which delivers the best performance under various conditions.
  • Realistic Simulation: To deliberate the execution of more complex models for the transmitter like LED array and receiver like camera with pixel array to emulate more realistic Optical Visual MIMO systems.
