How to Implement UAV based VANET in OMNeT++

To Implement a UAV-based Vehicular Ad-hoc Network (VANET) in OMNeT++ has needs to setup a network where UAVs and ground vehicles interact to enable the communication and optimize the network connectivity. This is done by INET Framework in OMNeT++.We share with you simulation results for your project in UAV based VANET in OMNeT++tool. The given below is the comprehensive approach to implement the UAV-based Vehicular Ad-hoc Network (VANET) in OMNeT++:

Step-by-Step Implementation

Install OMNeT++ and INET Framework

Make certain we have OMNeT++ and the INET Framework installed.

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 (e.g., UAVVANETSimulation).

Import INET into Your Project

Import INET: Right-click on your project in the Project Explorer, select Properties. Go to Project References and check the INET project.
Copy INET Examples: Copy example configurations from the INET framework to project for reference.

Define the Network Topology

Generate a new NED file to describe network topology that contains UAVs and vehicles.

Example: UAV-based VANET Topology (UAVVANETNetwork.ned)

package uavvanet;

import inet.node.inet.WirelessHost;

import inet.node.inet.Router;

network UAVVANETNetwork

{

parameters:

@display(“bgb=800,400”);

submodules:

vehicle1: WirelessHost {

@display(“p=100,300”);

}

vehicle2: WirelessHost {

@display(“p=300,300”);

}

vehicle3: WirelessHost {

@display(“p=500,300”);

}

uav1: WirelessHost {

@display(“p=200,100”);

}

uav2: 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];

uav1.wlan[0] <–> AdhocChannel <–> router.wlan[3];

uav2.wlan[0] <–> AdhocChannel <–> router.wlan[4];

@display(“bgb=600,400”);

}

In this example:

vehicle1, vehicle2, and vehicle3 are vehicles equipped with wireless communication capabilities.
Uav1 and uav2 are UAVs that assist in communication.
Router is a central node facilitating interact among the UAVs and vehicles.
The AdhocChannel is used for ad-hoc communication between nodes.

Configure the Simulation

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

Example: Configuration File (omnetpp.ini)

network = uavvanet.UAVVANETNetwork

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 = “uav1 uav2”

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

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

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

*.uav*.numApps = 1

*.uav*.app[0].typename = “UdpSink”

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

# UDP Configuration

*.vehicle*.hasUdp = true

*.uav*.hasUdp = true

# Wireless Configuration

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

*.uav*.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”)

*.uav1.ipv4.config = xmldoc(“uav1.xml”)

*.uav2.ipv4.config = xmldoc(“uav2.xml”)

Create IP Address Configuration Files

Generate XML files to describe the IP address configuration for each vehicle and UAV.

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 uav1 (uav1.xml)

</interface>

</config>

Example: IP Configuration File for uav2 (uav2.xml)

</interface>

</config>

Implement Communication Logic

To mimic the interaction among vehicles and UAVs, we need to execute 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 UAVs

}

Example: Simple UAV Application Logic (Pseudo-Code)

class UAVApp : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

private:

void receiveData();

};

void UAVApp::initialize() {

// Initialization code

}

void UAVApp::handleMessage(cMessage *msg) {

// Logic to handle received data

receiveData();

}

void UAVApp::receiveData() {

// Logic to process received data from vehicles

}

Run the Simulation

Build the Project: Right-click on your project and choose Build Project.
Run the Simulation: Click on the green play button in the OMNeT++ IDE to start the simulation.

Here, we demonstrate the complete procedures to execute the UAV-based Vehicular Ad-hoc Network that used to communicate with other vehicles to optimize the network connectivity that were implemented using the OMNeT++ simulator. Further details regarding the implementation of the UAV-based Vehicular Ad-hoc Network in various scenarios will be delivered.
