How to Implement Satellite Constellations 5G in OMNeT++

To implement satellite constellations for 5G networks in OMNeT++ has numerous steps to follow and the satellite networks establish the unique difficulties and characteristics.  The given below is the brief structure to set up and simulate satellite constellations in OMNeT++:

Step-by-Step Implementation:

1. Understand Satellite Constellations in 5G

• Satellite Constellations consist of multiple satellites working together to deliver the global coverage. In a 5G context, they can improve the connectivity that particularly in remote or underserved areas.

2. Set up OMNeT++ Environment

• Make sure we have OMNeT++ and the INET framework installed. The INET framework delivers the networking models that can be expanded or adjusted for satellite simulations.

3. Create a New Project

• Open OMNeT++ and generate a new project dedicated to satellite constellation simulation.

4. Define Network Topology

• Create Satellite and Ground Station Modules:
  • Use .ned files to describe network topology that contains the satellites, ground stations, and possibly user equipment.
  • Example:

network SatelliteConstellation

{

submodules:

satellite1: Satellite {

@display(“i=satellite”);

}

satellite2: Satellite {

@display(“i=satellite”);

}

groundStation: GroundStation {

@display(“i=groundstation”);

}

connections:

satellite1.out –> groundStation.in;

satellite2.out –> groundStation.in;

}

5. Define Satellite and Ground Station Behavior

• Create Satellite Modules:
  • Describe the behaviour of satellites, like their orbits, communication protocols, and handover processes.
  • Example:

simple Satellite

{

parameters:

double orbitAltitude = 500km;

gates:

inout out;

}

• Create Ground Station Modules:
  • State ground stations’ behaviour that encompasses the communication with satellites and user equipment.
  • Example:

simple GroundStation

{

parameters:

double antennaGain = 30dB;

gates:

inout in;

}

6. Implement Satellite Movement and Handover

• Define Movement and Handover:
  • Execute satellite movement to mimic their orbits and handover processes among satellites.
  • We need to write custom C++ code to emulate orbital mechanics and dynamic changes.
  • Example (simplified):

void Satellite::handleMessage(cMessage *msg)

{

// Update position based on orbital mechanics

// Handle handovers between satellites

}

7. Define Communication Protocols

• Simulate Communication:
  • Describe how satellites and ground stations communicate that has link budgets, data rates, and latency.
  • Use INET’s communication protocols as a base that acclimatising them for satellite-specific requirements.
  • Example:

void GroundStation::handleMessage(cMessage *msg)

{

// Handle incoming messages from satellites

// Implement communication protocols

}

8. Configure Simulation Parameters

• Edit the omnetpp.ini File:
  • Set simulation parameters like the number of satellites, their orbits, and communication settings.
  • Example:

[Config SatelliteConstellation]

network = SatelliteConstellation

**.satellite1.orbitAltitude = 500km

**.groundStation.antennaGain = 30dB

9. Run the Simulation

• Compile and Execute:
  • Compile project and run the simulation.
  • Use OMNeT++’s graphical tools to observe and evaluate the performance of the satellite constellation.

10. Analyse Results

• Evaluate Network Performance:
  • Evaluate the metrics like coverage, data throughput, handover efficiency, and latency.
  • Use OMNeT++’s analysis tools to visualize and deduce the outcomes.

In the end of manual, we clearly shown how the satellite constellation in 5G will execute and implement successfully using the OMNeT++ tool and also we plan to provide the additional details regarding the satellite constellation in 5G performs in other simulation tools.
