How to Start Molecular Communication Projects Using NS3

To start the Molecular Communication (MC) using NS3 that is an emerging field in nanonetworking, to replicate the interaction among nanoscale entities via molecules. For nanoscale simulations, molecular Communication needs certain modules, since traditional network simulators such as NS3 are not integrally modeled for molecular-based or diffusion-based interactions within NS3. But, we can employ extensions or custom-built modules in NS3 or incorporate NS3 along with particular molecular interaction simulators such as N3Sim or BiNS2.

Below is a basic approach on how to configure a Molecular Communication project in NS3.

Steps to Start Molecular Communication Projects in NS3

  1. Install NS3 and Required Extensions
  1. Download and Install NS3:

git clone https://gitlab.com/nsnam/ns-3-dev.git ns-3

cd ns-3

./waf configure –enable-examples –enable-tests

./waf build

  1. Explore Molecular Communication Extensions: While NS3 doesn’t support directly Molecular Communication allowing it we want extensions such as N3Sim or BiNS2 that are modeled particularly for replicating molecular communication on the nanoscale. These simulators may be incorporated along with NS3 making a complete environment.
    • N3Sim: For replicating molecular diffusion, we can utilize specialized simulator.
    • BiNS2: An NS3-compatible library invented for nano and molecular interaction simulations to expand NS3.
  2. Verify Installation by executing a simple instance such as a WiFi example, to check NS3 is correctly operating:

./waf –run=wifi-simple-adhoc

  1. Integrate Molecular Communication Modules

If we are utilising BiNS2:

  • Initially, we download and install BiNS2, a nanonetwork simulation module which incorporates molecular communication in NS3.
  • We adhere to any certain configuration guidelines to incorporate it with NS3 after installing BiNS2.

On the other hand, if we are involved within a standalone molecular interaction simulator such as N3Sim:

  • Replicate the molecular processes utilizing N3Sim. For higher-level network simulations, swapping data among them to use NS3 as required.
  1. Set Up Basic Molecular Communication Components

We will normally contain following components in the molecular communication network:

  • Transmitter Nanomachine: It distributes molecules to transfer data.
  • Receiver Nanomachine: Identifies the molecules that are distributed through the transmitter.
  • Molecular Channel: The medium like fluid or tissue in which from transmitter to receiver, molecules disperse.
  • Environment Properties: Set up diffusion features like temperature, viscosity, and diffusion coefficient.
  1. Define a Simple Molecular Communication Scenario

We describe the simple molecular communication configuration includes a transmitter and receiver within a bounded environment, from transmitter to receiver along with molecules diffusing. Here’s how to theoretically configure a basic simulation.

Example: Setting up Transmitter and Receiver Nodes (Conceptual Example)

Here’s the configuration approach, even though the accurate code according to the module that are utilized:

  1. Create Transmitter and Receiver Nodes: Signify the transmitter and receiver to utilize nodes within NS3. Every single node will distribute or identify molecules according to the parameters that are described within the molecular communication library.

// Pseudocode: Set up nodes as nanomachines

NodeContainer nanoNodes;

nanoNodes.Create(2); // Transmitter and Receiver

  1. Configure Molecular Channel Properties: In NS3, if the extension allows it or via the certain molecular simulator such as BiNS2 then configure parameters such as diffusion coefficient, molecule type, and environment dimensions.
  2. Define Diffusion Model: In the environment, set up the diffusion or propagation model for molecules.
  1. Implement Molecular Emission and Detection Processes

Describe the processes for molecular emission on the transmitter and molecule detection at the receiver. For instance:

  • Molecule Release: The transmitter releases molecules at certain intervals, to signify bits of data.
  • Molecule Detection: The receiver verifies occasionally for molecules and interprets its presence like a signal.
  1. Set Up Data Exchange and Signaling (in NS-3)

If we are utilizing NS3 signifying the higher-level network communications as handling according to the sensor data when activating the molecular releases then we can be used custom applications replicating molecular events such as data packets.

Example (using pseudo-code for molecular interactions):

// Pseudocode for emission and detection applications

ApplicationContainer apps;

apps.Add(transmitterApp); // Molecular emission at transmitter

apps.Add(receiverApp);    // Molecular detection at receiver

  1. Collect and Analyze Performance Metrics

We analyse the general performance parameters for Molecular Communication:

  • Propagation Delay: Duration attaining the receiver for molecules.
  • Bit Error Rate (BER): Estimate of errors within transmission since molecules probably erratically disperse.
  • Molecule Count at Receiver: We monitor the volume of molecules that are identified over time.
  • Throughput: Data rate successfully obtained on the receiver.

Observe these parameters since they don’t supported natively using NS3’s FlowMonitor or other standard modules.

  1. Visualize and Analyze Results
  1. Custom Visualization: Envision molecule diffusion utilizing 3D visualization software or export molecular locations.
  2. Plotting Tools: We transfer gathered parameters plotting performance features such as delay, error rate, and molecule count over time.
  1. Explore Advanced Scenarios in Molecular Communication

After configuring the basics, we can be discovered more complex situations like:

  • Channel Impairments: In environmental properties, we can design the obstacles, variable diffusion rates, or changes.
  • Multi-transmitter Systems: Configure several transmitters to interact with a unique receiver.
  • Adaptive Communication: Execute the feedback-based interaction in which transmitter depends on the environmental feedback modifies molecule release.

In the final, we had successfully explored the essential information and stepwise process that will support to start and analyse the Molecular Communication Projects then visualize it using NS3 simulation tool. If you require further information regarding this process we will offered that it too.
