How to Implement Drone based VANET in OMNeT++

To implement a drone-based Vehicular Ad-hoc Network (VANET) in OMNeT++ encompasses set up a network wherever drones and ground vehicles interconnect to simplify data interchange and increase network connectivity. By using the INET Framework in OMNeT++.

Here, is the step-by-step guide to executing a drone-based VANET in OMNeT++:

Step-by-Step Guide

Install OMNeT++ and INET Framework

To make a certain to have OMNeT++ and the INET Framework installed. To download it from their individual websites and go along with the installation instructions.

Create a New OMNeT++ Project

Open OMNeT++ IDE: Start the OMNeT++ IDE.
Create a New Project: Go to File -> New -> OMNeT++ Project. Name the project like DroneVANETSimulation.

Import INET into the Project

Import INET: Right-click on the project in the Project Explorer, choose Properties. Go to Project Positions and check the INET project.
Copy INET Examples: Copy sample conformations from the INET framework to the project for reference.

Define the Network Topology

To make a new NED file to define the network topology, including drones and vehicles.

Example:

Drone-based VANET Topology (DroneVANETNetwork.ned)

package dronevanet;

import inet.node.inet.WirelessHost;

import inet.node.inet.Router;

network DroneVANETNetwork

{

parameters:

@display(“bgb=800,400”);

submodules:

vehicle1: WirelessHost {

@display(“p=100,300”);

}

vehicle2: WirelessHost {

@display(“p=300,300”);

}

vehicle3: WirelessHost {

@display(“p=500,300”);

}

drone1: WirelessHost {

@display(“p=200,100”);

}

drone2: WirelessHost {

@display(“p=400,100”);

}

router: Router {

@display(“p=300,200”);

}

connections:

vehicle1.wlan[0] <–> AdhocChannel <–> router.wlan[0];

vehicle2.wlan[0] <–> AdhocChannel <–> router.wlan[1];

vehicle3.wlan[0] <–> AdhocChannel <–> router.wlan[2];

drone1.wlan[0] <–> AdhocChannel <–> router.wlan[3];

drone2.wlan[0] <–> AdhocChannel <–> router.wlan[4];

@display(“bgb=600,400”);

}

In this example:

vehicle1, vehicle2, and vehicle3 are vehicles equipped among wireless communication capabilities.
drone1 and drone2 are drones that help in communication.
router is a central node facilitating communication with the drones and vehicles.
The AdhocChannel is charity for ad-hoc communication among all nodes.

Configure the Simulation

To make an OMNeT++ initialization file to configure the parameters of the simulation.

Example:

Configuration File (omnetpp.ini)

[General]

network = dronevanet.DroneVANETNetwork

sim-time-limit = 100s

# Visualization

*.visualizer.canvasVisualizer.displayBackground = true

*.visualizer.canvasVisualizer.displayGrid = true

# Host Configuration

*.vehicle*.numApps = 1

*.vehicle*.app[0].typename = “UdpBasicApp”

*.vehicle*.app[0].destAddresses = “drone1 drone2”

*.vehicle*.app[0].destPort = 5000

*.vehicle*.app[0].messageLength = 1024B

*.vehicle*.app[0].sendInterval = 1s

*.drone*.numApps = 1

*.drone*.app[0].typename = “UdpSink”

*.drone*.app[0].localPort = 5000

# UDP Configuration

*.vehicle*.hasUdp = true

*.drone*.hasUdp = true

# Wireless Configuration

*.vehicle*.wlan[0].typename = “AdhocHost”

*.drone*.wlan[0].typename = “AdhocHost”

# IP Address Configuration

*.vehicle1.ipv4.config = xmldoc(“vehicle1.xml”)

*.vehicle2.ipv4.config = xmldoc(“vehicle2.xml”)

*.vehicle3.ipv4.config = xmldoc(“vehicle3.xml”)

*.drone1.ipv4.config = xmldoc(“drone1.xml”)

*.drone2.ipv4.config = xmldoc(“drone2.xml”)

Create IP Address Configuration Files

Produce XML files to state the IP address configuration for every vehicle and drone.

Example:

IP Configuration File for vehicle1 (vehicle1.xml)

</interface>

</config>

Example:

IP Configuration File for vehicle2 (vehicle2.xml)

</interface>

</config>

Example:

IP Configuration File for vehicle3 (vehicle3.xml)

</interface>

</config>

Example:

IP Configuration File for drone1 (drone1.xml)

</interface>

</config>

Example:

IP Configuration File for drone2 (drone2.xml)

</interface>

</config>

Implement Communication Logic

To suggest the communication among the vehicles and drones, need to implement the logic for data exchange.

Example:

Simple Communication Logic (Pseudo-Code)

class VehicleApp : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

private:

void sendData();

};

void VehicleApp::initialize() {

// Initialization code

scheduleAt(simTime() + 1, new cMessage(“sendData”));

}

void VehicleApp::handleMessage(cMessage *msg) {

if (strcmp(msg->getName(), “sendData”) == 0) {

sendData();

scheduleAt(simTime() + 1, msg);

} else {

// Handle other messages

}

void VehicleApp::sendData() {

// Logic to send data to drones

}

Example:

Simple Drone Application Logic (Pseudo-Code)

class DroneApp : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

private:

void receiveData();

};

void DroneApp::initialize() {

// Initialization code

}

void DroneApp::handleMessage(cMessage *msg) {

// Logic to handle received data

receiveData();

}

void DroneApp::receiveData() {

// Logic to process received data from vehicles

}
