How to Start V2X Communication Projects using OMNeT++
To create the V2X (Vehicle-to-Everything) communication projects using OMNeT++ have needs the integration of vehicular communication frameworks and the setting of specific scenarios and we replicate the interactions among vehicles and other entities such as infrastructure, pedestrians, and networks. Here’s a step-by-step procedure follow below the listed steps:
Steps to Start V2X Communication Projects using OMNeT++
- Install OMNeT++
- Download and Install: Get the latest OMNeT++.
- Verify Installation: Open the IDE and enable it introduce the successfully.
- Install and Set Up Required Frameworks
The V2X communication has includes the replicating the vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and other kinds of communication.
Recommended Frameworks:
- INET Framework: It offers the communication protocols and mobility models.
- Veins Framework: Intended for vehicular ad hoc networks (VANET) and integrates the OMNeT++ through SUMO (Simulation of Urban Mobility).
- SimuLTE (optional): For LTE and 5G-based vehicular communications.
Steps to Install Veins:
- Download Veins from its official page.
- Extract the Veins framework into your OMNeT++ workspace.
- Significance the project into the OMNeT++ IDE like as File > Import > Existing Projects.
- Install and Configure SUMO
SUMO is used for mobility replication in V2X projects.
- Download and Install: Get SUMO from SUMO’s official page.
- Configure SUMO:
- Enable the SUMO is in your system’s for setting the PATH environment variable.
- Configure the road network (.net.xml) and describe the routes for vehicles.
- Integrate SUMO with OMNeT++
- Veins integrates the SUMO through OMNeT++ for mobility replication.
- Utilized the TraCI such as Traffic Control Interface we control the vehicle movement and communicate mobility events to OMNeT++.
Example omnetpp.ini Configuration:
[General]
network = V2XNetwork
sim-time-limit = 100s
*.managerType = “TraCIMobility”
*.mobility.sumoConfigFile = “path/to/sumo/config.sumocfg”
*.mobility.sumoConnections = true
- Define V2X Communication Scenario
- Network Topology:
- Communication environment used the network topology for .ned files and we describe the vehicles, roadside units (RSUs), and other network elements.
Example .ned File:
network V2XNetwork
{
submodules:
vehicle[0..9]: VehicleNode; // Vehicles in the network
rsu: RoadsideUnit; // Roadside unit for V2I communication
connections:
vehicle[*].gate++ <–> rsu.gate++;
vehicle[*].gate++ <–> vehicle[*].gate++;
}
- Implement V2X Communication Logic
- Message Passing: Used their C++ we execute the vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication.
- Safety Messages: Replicate the secured periodic beacon messages for collision avoidance.
- Event-Driven Messages: Execute the event-triggered messages for sample the traffic accidents.
Example C++ Code for V2V Communication:
void VehicleNode::sendSafetyMessage()
{
SafetyMessage *msg = new SafetyMessage(“SafetyMsg”);
msg->setSenderId(getId());
msg->setLocation(getCurrentPosition());
send(msg, “out”);
}
void VehicleNode::handleMessage(cMessage *msg)
{
SafetyMessage *safetyMsg = check_and_cast<SafetyMessage *>(msg);
EV << “Received safety message from ” << safetyMsg->getSenderId() << “\n”;
}
- Configure Simulation Parameters
- Setting the communication parameters metrices such as frequency, range, and message size in the omnetpp.ini file.
Example omnetpp.ini:
[General]
*.communicationRange = 300m
*.beaconInterval = 100ms
*.channelFrequency = 5.9GHz
*.messageSize = 200Bytes
- Run and Debug the Simulation
- Run Simulation:
- Start SUMO with your .sumocfg file.
- Introduction the OMNeT++ and evaluate the replication.
- Visualize:
- Show the mobility in the SUMO GUI and network communication for the OMNeT++ GU
- Analyze Results
- Metrics to Measure:
- Packet delivery ratio.
- Latency.
- Communication range effects.
- Impact of mobility on message delivery.
- Tools:
- OMNeT++’s result analysis tools for .sca and .vec files.
- Transfer the results for visualization in external tools such as MATLAB or Python.
- Enhance the Project
- Advanced Features:
- Enhance the LTE or 5G connectivity using SimuLTE.
- Replicate the advanced characteristics for edge computing in the real-time decision-making.
- Scenarios:
- The Multi-hop V2V communication for traffic warnings scenarios for the enhancement.
- The Hybrid environment for V2X communication joining the DSRC and LTE/5G.
- communicate the vehicle emergency.
Example V2X Use Cases
- Collision Avoidance:
- The vehicles are broadcast secure messages we avoid the collisions at intersections.
- Traffic Management:
- The congestion management for RSUs organize the traffic flow using V2I communication.
- Platooning:
- Replicate the platooning vehicles for traveling in the coordinated groups.
- Edge-Assisted V2X:
- Utilized the edge- assisted V2X for RSUs the real-time data processing and decision-making.
In this page, we clearly showed the simulation process on how the V2X (Vehicle-to-Everything) Communication perform in the OMNeT++ tool and also, we presented the complete elaborated explanation to understand the concept of the simulation. Additional clarification will be provided in a new document if necessary.
