How to Start Distance Vector Routing Projects Using OMNeT++

To start a Distance Vector Routing (DVR) project using OMNeT++ has numerous key steps. Below is a general instruction to get started:

Steps to Start DVR Projects in OMNeT++

  1. Set Up OMNeT++ Environment
  • Install OMNeT++:
    • We should download and install OMNeT++ environment on the system.
    • Adhere to the installation guidance based on the operating system.
  • Install INET Framework:
    • Most routing protocols with DVR utilise the INET framework.
    • We download the INET framework with OMNeT++ version.
    • Construct the INET framework to utilise the following command:

make makefiles

make

  1. Understand the Distance Vector Routing Protocol
  • Define the DVR principles:
    • Routers periodically swap distance vectors.
    • Every single router modernizes their routing table depends on the received vectors.
    • Execute the Bellman-Ford mechanisms for route computation.
  1. Plan Your Simulation
  • Describe the project needs like:
    • Volume of nodes or routers.
    • Network topology such as mesh, star, or tree.
    • Traffic patterns (e.g., constant bit rate, random).
    • Evaluation parameters like latency, packet delivery ratio.
  1. Configure a New OMNeT++ Project
  1. Create a New Project:
    • Go to OMNeT++ IDE.
    • Make a new project by directing to File > New > OMNeT++ Project.
  2. Include INET:
    • Integrate the INET framework to the all dependencies of project:
      • Right-click on the project → Properties > Project References.
      • Choose the INET framework.
  1. Implement Distance Vector Routing
  • Routing Module:
    • Execute a custom routing module or prolong an existing one using INET framework.
    • Execute the DVR logic like:
      • Route updates through Bellman-Ford mechanisms.
      • Periodic exchange of distance vectors.
  • Network Layer Integration:
    • Incorporate routing protocol including the INET network layer which is normally IPv4NetworkLayer.
  • Modify .ned Files:
    • Create a network topology and node connections using .ned files.
    • Instance:

network DistanceVectorNetwork

{

submodules:

router[10]: StandardHost {

parameters:

@display(“i=device/router”);

routingProtocol = “DistanceVectorRouting”;

}

}

  1. Add Traffic Sources
  • Make use of traffic-generating applications such as UDP or TCP.
  • Set the traffic patterns using .ini files.
  1. Write Simulation Configurations
  • Set the simulation metrics using the omnetpp.ini file:

[Config DistanceVectorSimulation]

network = DistanceVectorNetwork

*.router*.app[0].destAddress = “10.0.0.2”

  1. Test and Debug
  • We need to execute the simulations to make sure that protocol properly functions.
  • To envision and debug with the help of OMNeT++’s Tkenv GUI.
  • Record errors or unexpected behaviors.
  1. Analyze Results
  • Analyse the parameters such as latency, throughput, and packet loss to utilise OMNeT++’s built-in tools.
  • Optionally, we need to utilise external tools like MATLAB or Python for further data analysis and visualization.
  1. Expand and Optimize
  • Develop the protocol including:
    • Energy efficiency.
    • Dynamic topology changes.
    • Link failure handling.
  • We need to equate with other routing protocols such as Link State Routing or AODV for performance estimation.
