How to Start PEGASIS Protocol Projects using OMNeT++

To stimulate a project executing the PEGASIS (Power-Efficient GAthering in Sensor Information System) protocol in OMNeT++, observe the procedures for the below. PEGASIS is a hierarchical clustering protocol used in wireless sensor networks (WSNs) we enhance the energy efficiency through forming clusters and decreasing the number of direct communication connection.

Here’s a detailed guide on how to set up a PEGASIS protocol project in OMNeT++:

Steps to Start PEGASIS Protocol Projects using OMNeT++

  1. Install OMNeT++ and INET Framework

Previous method we initialize the working on the PEGASIS protocol, assure which we have the OMNeT++ and the INET Framework has installed, as this will be offers the basic structure for your replication.

Install OMNeT++:

  1. Download OMNeT++ from the official site.
  2. Track the installation techniques for your operating system such as Linux, Windows, macOS.
  3. Setting your environment and compile OMNeT++.

Install INET Framework:

  1. Clone the INET repository:

git clone https://github.com/inet-framework/inet.git

cd inet

  1. Build INET:

./configure

make

  1. Understand PEGASIS Protocol

PEGASIS is a hierarchical clustering protocol which concentrates on the energy-efficient transmission in wireless sensor networks. It works through:

  • Forming clusters of sensor nodes through one “cluster head” in every cluster.
  • Cluster heads transmission with every other and through the base station.
  • Nodes are communicating directly through the cluster head for decreasing the transmission overhead and energy usage.
  • The protocol needs a leader election between nodes we choose the cluster head and multi-hop communication for data transmission.
  1. Check for Existing PEGASIS Implementations in OMNeT++

OMNeT++’s INET Framework and other general collection typically concentrate on other routing protocols such as AODV, DSDV, OLSR, etc. PEGASIS cannot be possible directly as part of the INET framework, so we will likely require to implement PEGASIS yourself or find an existing third-party execution.

Option 1: Use an Existing PEGASIS Implementation

  • Search in INET: Checked the INET repository or the OMNeT++ community to see if PEGASIS has been executed and shared via other users. There may be community-driven projects which have improved the PEGASIS to OMNeT++.
  • GitHub and Research Papers: We can also detect for open-source PEGASIS executions on platforms such as GitHub or in academic papers that share replication of the code.

Option 2: Implement PEGASIS Yourself

If no appropriate for execution is found, we will require the develop the PEGASIS protocol from scratch.

To execute the PEGASIS, we will necessary to:

  • State the cluster formation process on how the nodes select their cluster heads.
  • Execute the leader election technique we select a node as the cluster head.
  • Describe the multi-hop communication among nodes and cluster heads.
  • Implement the communication model: Nodes are communicating the cluster head using decrease the transmission power and cluster heads communicate through the base station or other cluster heads.
  1. Create the Network Topology Using NED Files

Next execute the PEGASIS protocol, we can build a NED file which describe the network topology. This topology signifies the arrangement of nodes for base stations and communication connection in the replication.

Example NED File for PEGASIS Topology:

Here’s a simple example of a network with nodes and a base station:

network PEGASISNetwork {

submodules:

baseStation: SensorNode {

@display(“p=300,300”);

}

node1: SensorNode {

@display(“p=100,100”);

}

node2: SensorNode {

@display(“p=200,100”);

}

node3: SensorNode {

@display(“p=100,200”);

}

node4: SensorNode {

@display(“p=200,200”);

}

connections:

node1.eth++ <–> baseStation.eth++;

node2.eth++ <–> baseStation.eth++;

node3.eth++ <–> baseStation.eth++;

node4.eth++ <–> baseStation.eth++;

}

This example describes a simple sensor network through four sensor nodes and a base station. We can extend this topology through improve the more nodes for adjusting their positions and incorporating further complex communication models.

  1. Configure the Simulation Using the INI File

Next, we will describe the replication parameters metrices in an INI file. The INI file specifies the configure the replication such as simulation time of routing protocols and node setting.

Example INI File for PEGASIS Network:

[General]

network = PEGASISNetwork

sim-time-limit = 100s

# PEGASIS-specific settings (if implemented)

*.node1.routingProtocol = “PEGASIS”

*.node2.routingProtocol = “PEGASIS”

*.node3.routingProtocol = “PEGASIS”

*.node4.routingProtocol = “PEGASIS”

# Transmission power settings

*.node1.transmissionPower = 0.5mW

*.node2.transmissionPower = 0.5mW

*.node3.transmissionPower = 0.5mW

*.node4.transmissionPower = 0.5mW

# Cluster-head election settings (example)

*.node1.clusterHead = false

*.node2.clusterHead = true

*.node3.clusterHead = false

*.node4.clusterHead = true

# Mobility model (if nodes are mobile)

*.node1.mobility = “RandomWaypointMobility”

*.node2.mobility = “RandomWaypointMobility”

*.node3.mobility = “RandomWaypointMobility”

*.node4.mobility = “RandomWaypointMobility”

# Statistics collection

*.vector-recording = true

*.scalar-recording = true

This configuration:

  • Set up the RIP protocol for every node such as you can replace this with your PEGASIS protocol.
  • Describe the transmission power for nodes.
  • Requires that nodes are cluster heads.
  • Optionally has involves the mobility models for mobile nodes such as random waypoint mobility.
  • Ensure scalar and vector recording we seizure the replication of parameter metrics.
  1. Implementing PEGASIS Protocol Logic

In order to execute the PEGASIS from scratch in OMNeT++, we will need to:

  1. Create the Protocol Logic: Describes the core behaviour of PEGASIS, has involves they are:
    • Leader election and cluster formation.
    • Data aggregation and communication among cluster heads.
    • Base station is the data transmission.

This have included the making a message kind like as cluster head announcement messages, data aggregation messages, and data transmission messages.

  1. Define the Protocol Logic in C++: we will write the code for PEGASIS in C++. Build a module that maintains the election process for the formation of clusters the sending/receiving of data and the multi-hop communication logic.

Example Protocol Module in C++:

Here’s a very basic skeleton of how the C++ code might look:

#include <omnetpp.h>

class PEGASISNode : public cSimpleModule {

private:

bool isClusterHead;

int clusterHeadId;

protected:

virtual void initialize() override {

// Initialize node parameters

isClusterHead = par(“isClusterHead”);

clusterHeadId = -1;

// Set up initial communication behavior

}

 

virtual void handleMessage(cMessage *msg) override {

if (isClusterHead) {

// Handle communication as cluster head

} else {

// Handle communication as a regular node

}

// Send or receive data, handle leader election

}

virtual void finish() override {

// Gather statistics and finalize simulation results

}

};

Define_Module(PEGASISNode);

In this example:

  • isClusterHead describe the whether node is a cluster head.
  • You will write the actual logic for maintaining the messages such as leader election, data aggregation, and communication.
  • We can improve the more sophisticated logic for cluster head selection for energy usage and data routing.
  1. Build and Run the Simulation
  1. Compile the Project: If we are using the OMNeT++ IDE, create the project by choosing the Build Project.
  2. Run the Simulation: Used the process for command line or OMNeT++ IDE we initialize the replication:

./run -u Cmdenv

  1. We can also process in the Tkenv for graphical replication and visualization of movements.
  1. Monitor and Analyze Results

Once the replication is process, we can:

  • Used the follow on OMNeT++’s scalar and vector output to observe the performance, such as energy usage, packet delivery, and network lifetime.
  • Use plotting tools in OMNeT++ to visualize parameter metrics such as data aggregation, number of hops, and cluster formation.
  • Distribute the outcomes for further study with tools such as Python or Excel.
  1. Extend and Experiment

Once you have a basic simulation working, you can:

  • Experiment with larger networks: Validate on how the PEGASIS scales through further nodes and larger network sizes.
  • Energy consumption models: Incorporate more detailed energy models we realize on how energy-efficient PEGASIS will performs.

With the help of this procedure you can obtain the knowledge and can be able to simulate the Power-Efficient GAthering in Sensor Information System) protocol in OMNeT++. This simple structure replicates the PEGASIS protocol in OMNeT++. Additional specific details about the Power-Efficient GAthering in Sensor Information System project also provided.
