How to Implement Intelligent Agent WSN in OMNeT++

To implement an Intelligent Agent in a Wireless Sensor Network (WSN) using OMNeT++, depends on the aggregated data, sensor nodes could independently make decisions and also communicate with one another by organizing the network. In OMNeT++, INET framework offers to build this network. Here, we are providing step-by-step guide to implementing an Intelligent Agent WSN in OMNeT++:

Step-by-Step Implementation:

Install OMNeT++ and INET Framework

Make certain to install both OMNeT++ and the INET Framework on your computer.

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 (for instance: IntelligentAgentWSN).

Import INET into Your Project

Import INET: In Project Explorer, Right-click on project, select Properties. Go to Project References and check the INET project.
Copy INET Examples: For reference, we have to replicate the example configurations from the INET framework to the project.

Define the Network Topology

Create a new NED file to state the network topology that has sensor nodes and a sink node.

Example: Intelligent Agent WSN Topology (IntelligentAgentWSN.ned)

package intelligentagentwsn;

import inet.node.inet.WirelessHost;

import inet.node.inet.SensorNode;

import inet.node.inet.SinkNode;

network IntelligentAgentWSN

{

parameters:

@display(“bgb=800,400”);

submodules:

sensorNode1: SensorNode {

@display(“p=100,300”);

}

sensorNode2: SensorNode {

@display(“p=300,300”);

}

sensorNode3: SensorNode {

@display(“p=500,300”);

}

sensorNode4: SensorNode {

@display(“p=700,300”);

}

sinkNode: SinkNode {

@display(“p=400,100”);

}

In this instance:

sensorNode1, sensorNode2, sensorNode3, and sensorNode4 are sensor nodes.
sinkNode is a sink node that is used to aggregate the data from sensor nodes.

Configure the Simulation

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

Example: Configuration File (omnetpp.ini)

network = intelligentagentwsn.IntelligentAgentWSN

sim-time-limit = 100s

# Visualization

*.visualizer.canvasVisualizer.displayBackground = true

*.visualizer.canvasVisualizer.displayGrid = true

# Sensor Node Configuration

*.sensorNode*.numApps = 1

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

*.sensorNode*.app[0].destAddresses = “sinkNode”

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

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

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

# Sink Node Configuration

*.sinkNode.numApps = 1

*.sinkNode.app[0].typename = “UdpSink”

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

# UDP Configuration

*.sensorNode*.hasUdp = true

*.sinkNode.hasUdp = true

# IP Address Configuration

*.sensorNode1.ipv4.config = xmldoc(“sensorNode1.xml”)

*.sensorNode2.ipv4.config = xmldoc(“sensorNode2.xml”)

*.sensorNode3.ipv4.config = xmldoc(“sensorNode3.xml”)

*.sensorNode4.ipv4.config = xmldoc(“sensorNode4.xml”)

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

Create IP Address Configuration Files

Every sensor node and sink node should allocate the IP address configuration by making XML files.

Example: IP Configuration File for sensorNode1 (sensorNode1.xml)

</interface>

<route>

</route>

</routing>

</config>

Example: IP Configuration File for sensorNode2 (sensorNode2.xml)

</interface>

<route>

</route>

</routing>

</config>

Example: IP Configuration File for sensorNode3 (sensorNode3.xml)

</interface>

<route>

</route>

</routing>

</config>

Example: IP Configuration File for sensorNode4 (sensorNode4.xml)

</interface>

<route>

</route>

</routing>

</config>

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

</interface>

</config>

Implement Intelligent Agent Logic

We have to execute decision-making logic in the sensor node application, to simulate intelligent agents in sensor nodes.

Example: Simple Intelligent Agent Logic (Pseudo-Code)

class IntelligentAgentApp : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

private:

void processSensorData();

void makeDecision();

void sendData();

};

void IntelligentAgentApp::initialize() {

// Initialization code

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

}

void IntelligentAgentApp::handleMessage(cMessage *msg) {

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

processSensorData();

makeDecision();

sendData();

scheduleAt(simTime() + 1, msg);

} else {

// Handle other messages

}

void IntelligentAgentApp::processSensorData() {

// Logic to process sensor data

}

void IntelligentAgentApp::makeDecision() {

// Logic to make decisions based on processed data

}

void IntelligentAgentApp::sendData() {

// Logic to send data to the sink node

}

Run the Simulation

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