How to Start Flooding Routing Projects using OMNeT++

To stimulate the Flooding routing is a simple yet essential concept in networking, in which each node transmits the received packets to overall the neighbours excepting the source. Estimate a Flooding Routing project in OMNeT++ has been involves the generating a network replication in which this routing strategy is applied. Here’s a step-by-step guide to help you get started:

Steps to Start Flooding Routing Projects using OMNeT++

  1. Set Up the Environment

Install OMNeT++

  • Download OMNeT++ from the official website and install it.
  • Assure the installation is working through process the sample replication.

Install INET Framework

  • Download the INET framework compatible through your OMNeT++ version.
  • Create the framework:

make makefiles

make

  1. Understand Flooding Routing
  • Basic Idea:
    • The node broadcasts for packet to the neighbours.
    • Every neighbour more broadcasts to their neighbours, assuring the overall nodes receive the packet.
    • Mechanisms such as sequence numbers or TTL (Time-To-Live) are used to avoid the infinite loops and duplicate transmissions.
  • Applications:
    • Network discovery.
    • Propagating control messages.
  1. Plan the Simulation

Define Objectives

  • Replicate a flooding routing mechanism.
  • Calculate the performance metrics such as:
    • Number of duplicate packets.
    • Network overhead.
    • Time to deliver packets to overall nodes.

Network Topology

  • Select a topology for sample grid, ring, or random.
  • Describe the number of nodes and connected the links.
  1. Create a New OMNeT++ Project
  1. Open OMNeT++ IDE.
  2. Go to File > New > OMNeT++ Project.
  3. Name your project for sample FloodingRouting and click Finish.
  1. Implement Flooding Routing

Define the Network Topology

  • Build a .ned file we describe the network structure.
  • Example:

network FloodingNetwork

{

submodules:

node[10]: StandardHost {

parameters:

@display(“i=device/router”);

}

connections:

node[*].pppg++ <–> node[*].pppg++;

}

Create a Custom Routing Module

  • Estimate a new flooding routing module through encompass the INET’s base classes.
  • Sample code for flooding logic:

class FloodingRouting : public cSimpleModule {

private:

std::set<int> receivedMessages; // To track processed messages

protected:

virtual void handleMessage(cMessage *msg) override {

auto packet = check_and_cast<Packet *>(msg);

// Prevent duplicate processing

int messageId = packet->getId();

if (receivedMessages.find(messageId) != receivedMessages.end()) {

delete packet;

return;

}

receivedMessages.insert(messageId);

// Forward the packet to all neighbors

for (int i = 0; i < gateSize(“out”); i++) {

if (packet->getArrivalGate() == gate(“in”, i)) continue; // Avoid sending back to the source

auto copy = packet->dup();

send(copy, “out”, i);

}

 

// Process locally if needed

processPacket(packet);

}

virtual void processPacket(Packet *packet) {

// Logic for processing packets locally

}

};

Integrate the Module

  • Enhance the new routing module to the nodes in your .ned file:

node[*]: StandardHost {

parameters:

routingProtocol = “FloodingRouting”;

}

  1. Configure Simulation Parameters
  • Add configurations in the omnetpp.ini file:

[Config FloodingRoutingSimulation]

network = FloodingNetwork

**.app[0].typename = “FloodingApp”

**.app[0].startTime = 1s

**.ttl = 10

  • Describe the parameters such as TTL to find the packet propagation depth.
  1. Run the Simulation
  • Open Tkenv or Cmdenv in OMNeT++ we process the replication.
  • Observe:
    • Packet flow with the network.
    • The number of duplicate packets.
  1. Analyze Results

Metrics to Evaluate

  • Delivery Ratio: How many nodes received the packet in a delivery ratio.
  • Overhead: Number of duplicate packets transfer the overhead.
  • Latency: Time to reach overall nodes.

Visualization

  • Used the visualize for OMNeT++’s built-in tools we display the packet flows and node communications.
  • Distribute the outcomes to tools such as MATLAB or Python for more analysis.
  1. Extend and Optimize

Introduce Improvements

  • Enhance the sequence numbers of packets we prevent the duplicates.
  • Execute the TTL to detect the packet propagation.
  • Used the selective flooding and we find the particular network regions.

Compare with Other Protocols

  • Estimate the flooding against further protocols such as OSPF or AODV.

Dynamic Topologies

  • Replicate the environment through connection failures or mobile nodes.
