How to Implement Interact Different Networks in OMNeT++

To implement the interaction between different networks in OMNeT++has normally encompasses making a simulation where numerous networks are stated, and communication among these networks is founded via gateways or routers. Given below is step-by-step approaches with instances on how to attain this:

Step-by-Step Implementations:

Step 1: Set Up the OMNeT++ Environment

Make certain that OMNeT++ and its related libraries, like INET, are installed and configured appropriately.

Step 2: Define the Network Models

State the different networks we need to emulate. Each network can have its own nodes, protocols, and configurations.

Example Network Definitions

// Define Network 1

network Network1

{

submodules:

host1: StandardHost;

host2: StandardHost;

router1: Router;

connections:

host1.ethg++ <–> EthernetCable <–> router1.ethg++;

host2.ethg++ <–> EthernetCable <–> router1.ethg++;

}

// Define Network 2

network Network2

{

submodules:

host3: StandardHost;

host4: StandardHost;

router2: Router;

connections:

host3.ethg++ <–> EthernetCable <–> router2.ethg++;

host4.ethg++ <–> EthernetCable <–> router2.ethg++;

}

Step 3: Create a Gateway or Router for Inter-Network Communication

A router or gateway is essential to permit communication among numerous networks.

Example Gateway Definition

// Define the Inter-Network Gateway

network Gateway

{

submodules:

router1: Router;

router2: Router;

connections:

router1.ethg++ <–> EthernetCable <–> router2.ethg++;

}

Step 4: Integrate Networks through the Gateway

Now, incorporate the described networks and the gateway to permit interaction among them.

Example Integrated Network Definition

// Define the Complete Network with Interaction

network CompleteNetwork

{

submodules:

net1: Network1;

net2: Network2;

gateway: Gateway;

connections allowunconnected:

net1.router1.ethg++ <–> EthernetCable <–> gateway.router1.ethg++;

net2.router2.ethg++ <–> EthernetCable <–> gateway.router2.ethg++;

}

Step 5: Configure the Simulation Parameters

Configure the simulation parameters like IP addressing, routing tables, and other needed parameters in the .ini file.

Example Configuration

[General]

network = CompleteNetwork

sim-time-limit = 100s

*.net1.host1.ipv4.address = “192.168.1.1”

*.net1.host2.ipv4.address = “192.168.1.2”

*.net1.router1.ipv4.address = “192.168.1.254”

*.net2.host3.ipv4.address = “192.168.2.1”

*.net2.host4.ipv4.address = “192.168.2.2”

*.net2.router2.ipv4.address = “192.168.2.254”

*.gateway.router1.ipv4.address = “10.0.0.1”

*.gateway.router2.ipv4.address = “10.0.0.2”

*.net1.router1.ipv4.routingTable[0].destAddress = “192.168.2.0”;

*.net1.router1.ipv4.routingTable[0].netmask = “255.255.255.0”;

*.net1.router1.ipv4.routingTable[0].gateway = “10.0.0.2”;

*.net1.router1.ipv4.routingTable[0].interfaceName = “ethg++”;

*.net2.router2.ipv4.routingTable[0].destAddress = “192.168.1.0”;

*.net2.router2.ipv4.routingTable[0].netmask = “255.255.255.0”;

*.net2.router2.ipv4.routingTable[0].gateway = “10.0.0.1”;

*.net2.router2.ipv4.routingTable[0].interfaceName = “ethg++”;

Step 6: Implement and Run the Simulation

When everything is configured, compile and run the simulation. Monitor how the nodes in different networks interact through the gateway.

Step 7: Analyse the Results

After running the simulation, we can use OMNeT++’s analysis tools to check the results and authenticate that the interaction among the networks is happening as expected.
