How to Start Network Routing Projects using OMNeT++

To stimulate the Network Routing projects in OMNeT++ has includes the modelling and replicating the routing protocols we analysis their performance in several network environment. The OMNeT++ offers the flexibility for executing the routing algorithms and testing them under various conditions. Frameworks such as INET can be assist the designing wired or wireless routing protocols.

Here’s a step-by-step for following below procedures:

Steps to Start Network Routing Projects using OMNeT++

  1. Install OMNeT++
  • Download: Get the latest version.
  • Install: Follow the steps for your operating system.
  • Verify: Open the OMNeT++ IDE we confirm the successful installation.
  1. Install Required Frameworks

We replicate the network routing; you require the frameworks which includes the routing protocol support.

Frameworks:

  1. INET Framework:
    • INET Framework involves the routing protocols such as OSPF, RIP, AODV, and DSR.
    • Download from INET’s official page.
  2. Custom Modules:
    • If executing the custom routing protocols, we can use their base OMNeT++ environment or extend the INET framework.

Installation Steps:

  1. Download the framework.
  2. Excerpt the files into your OMNeT++ workspace.
  3. Import the project into the IDE such as File > Import > Existing Projects.
  4. Create the framework in the OMNeT++ IDE.
  1. Define Your Project Scope

Decide on the kind of network routing we replicate:

  • Static Routing: The static are predefined routes among nodes.
  • Dynamic Routing: The dynamic routing protocols such as OSPF, AODV, or DSR.
  • Ad Hoc Networks: Infrastructure-less networks with dynamic routing for Ad Hoc Networks.
  • Custom Routing Protocols: Execute and validate your algorithm.
  1. Design the Network Topology

Utilized their network topology designs .ned files we describe the network that includes routers, hosts, and connections.

Example. ned File for Static Routing:

network StaticRoutingNetwork

{

submodules:

router[0..2]: Router;       // Three routers

hostA: StandardHost;       // Source host

hostB: StandardHost;       // Destination host

connections:

hostA.gate++ <–> router[0].gate++;

router[0].gate++ <–> router[1].gate++;

router[1].gate++ <–> router[2].gate++;

router[2].gate++ <–> hostB.gate++;

}

Example .ned File for Dynamic Routing:

network DynamicRoutingNetwork

{

submodules:

node[0..9]: WirelessNode; // Ten nodes for dynamic routing

connections:

node[*].wlan <–> node[*].wlan; // Wireless links

}

  1. Implement Routing Logic
  • Static Routing:
    • The static routing predefines routes manually in the omnetpp.ini file or through C++ code.
  • Dynamic Routing:
    • Utilized the built-in protocols such as AODV, DSR, or OSPF from the INET framework.
  • Custom Routing:
    • Write your own routing logic in C++.

Example C++ Code for Custom Routing:

void Router::handlePacket(Packet *pkt)

{

if (isDestination(pkt))

{

deliverPacket(pkt);

}

else

{

int nextHop = routingTable.getNextHop(pkt->getDestination());

send(pkt, “gate$o”, nextHop);

}

}

  1. Configure the Simulation

Setting the routing parameters of node attributes and replication of duration in the omnetpp.ini file.

Example Configuration for Static Routing:

[General]

network = StaticRoutingNetwork

sim-time-limit = 100s

*.router[0].routingTable = “router0.routes”

*.router[1].routingTable = “router1.routes”

*.router[2].routingTable = “router2.routes”

Example Configuration for AODV:

[General]

network = DynamicRoutingNetwork

sim-time-limit = 300s

*.node[*].protocolType = “AODV”

*.node[*].applicationType = “UdpBasicApp”

*.node[*].application.destAddress = “node[9]”

*.node[*].application.messageLength = 512

*.node[*].application.sendInterval = uniform(0.5s, 1s)

  1. Simulate Mobility (Optional)

Enhance the mobility we replicate their dynamic environment for wireless routing protocols.

Example Mobility Configuration:

[General]

*.node[*].mobilityType = “RandomWaypointMobility”

*.node[*].mobility.speed = uniform(1, 10)  # Random speed between 1 and 10 m/s

*.node[*].mobility.bounds = “0,0,500,500”  # Simulation area

  1. Run the Simulation
  • Run Simulation:
    • Right-click on the .ini file and select Run As > OMNeT++ replication.
  • Debugging:
    • Used the debugging their logs and visualizations we observe the routing table updates and packet flows.
  1. Analyze Results
  • Metrics to Evaluate:
    • Packet delivery ratio.
    • Routing overhead such as control packets.
    • Latency and jitter.
    • Network throughput.
  • Tools for Analysis:
    • Utilized their OMNeT++’s built-in analysis tools we show them. sca and .vec files.
    • Export the results to Python, MATLAB, or Excel for further analysis.

From the demonstration we completely aggregate the information about the installation process and simulation procedure for Network Routing projects that were deploy in the tool of OMNeT++. We provide the more answer, we will recruit a different guide.
