How to Implement 3D Wireless Sensor Modeling in OMNeT++

To implement 3D wireless sensor modelling in OMNeT++ has needs to encompass to emulate the scenarios where sensor nodes are placed and performs in a three-dimensional space and this can be helpful for modelling the networks in the scenarios like smart buildings, urban areas, or outdoor terrains where elevation and spatial distribution matter. The given below are the procedures on how to setup and simulate 3D wireless sensor networks in OMNeT++:

Step-by-Step Implementation:

1. Understand 3D Wireless Sensor Networks

In a 3D wireless sensor network:

• Nodes are positioned in 3D Space: In sensor nodes have X, Y, and Z coordinates.
• Communication is affected by 3D Distance: Communication and Signal propagation can be swayed by the 3D distance among the nodes.

2. Set up OMNeT++ Environment

Make sure OMNeT++ and the INET framework is installed. An OMNeT++ offer the simulation environment, and INET has encompasses the network models that can expand for 3D scenarios.

3. Create a New OMNeT++ Project

Open OMNeT++ and generate a novel project for 3D wireless sensor network simulation.

4. Define 3D Network Topology

Describe the network components and their 3D positions in .ned files.  We will want to expand or customize the existing modules to help the 3D positioning.

Example:

network WirelessSensorNetwork3D

{

submodules:

sensor1: SensorNode {

@display(“i=sensor;is=sensor;x=0;y=0;z=0”);

}

sensor2: SensorNode {

@display(“i=sensor;is=sensor;x=100;y=100;z=10”);

}

sensor3: SensorNode {

@display(“i=sensor;is=sensor;x=200;y=50;z=20”);

}

connections:

sensor1.out –> sensor2.in;

sensor2.out –> sensor3.in;

}

5. Extend Sensor Node Module

Generate or adjust the sensor node module to manage the 3D coordinates. Update the position handling to consider X, Y, and Z coordinates.

Example:

simple SensorNode

{

parameters:

double x = 0; // X-coordinate

double y = 0; // Y-coordinate

double z = 0; // Z-coordinate

gates:

inout in;

inout out;

}

6. Implement 3D Positioning in C++

Update the C++ code for the sensor nodes to manage the 3D positioning. This contains to initializing and updating the X, Y, and Z coordinates, and using these coordinates for communication and distance calculations.

Example:

class SensorNode : public cSimpleModule

{

private:

double x;

double y;

double z;

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

double calculateDistance(const SensorNode *otherNode) const;

public:

std::tuple<double, double, double> getPosition() const;

};

void SensorNode::initialize()

{

x = par(“x”);

y = par(“y”);

z = par(“z”);

}

void SensorNode::handleMessage(cMessage *msg)

{

// Handle incoming messages

// Implement communication and data processing

}

double SensorNode::calculateDistance(const SensorNode *otherNode) const

{

double dx = x – otherNode->x;

double dy = y – otherNode->y;

double dz = z – otherNode->z;

return sqrt(dx * dx + dy * dy + dz * dz);

}

std::tuple<double, double, double> SensorNode::getPosition() const

{

return std::make_tuple(x, y, z);

}

7. Configure Simulation Parameters

Run the omnetpp.ini file to set metrics relevant to the 3D positioning of sensor nodes.

Example:

[Config WirelessSensorNetwork3D]

network = WirelessSensorNetwork3D

**.sensor1.x = 0

**.sensor1.y = 0

**.sensor1.z = 0

**.sensor2.x = 100

**.sensor2.y = 100

**.sensor2.z = 10

**.sensor3.x = 200

**.sensor3.y = 50

**.sensor3.z = 20

8. Run the Simulation

Compile and execute the simulation. Observe how the 3D positioning of sensor nodes impacts the network performance like communication coverage, data routing, and signal strength.

9. Analyse Results

Evaluate performance metrics such as:

• Coverage: How well the 3D placement of nodes covers the intended area.
• Connectivity: Influence of 3D positioning on network connectivity and communication paths.
• Performance Metrics: In a 3D context the relevant parameter such as Network throughput, latency.

To interpret the outcomes of the simulation use OMNeT++’s analysis tools and visualization features.
