How to Start DSDV Protocol Projects Using OMNeT++

To start a Destination-Sequenced Distance Vector (DSDV) protocol using OMNeT++, we require configuring the OMNeT++ environment to utilise or enhance the execution of DSDV, then setting up and executing the simulation. DSDV is a proactive routing protocol which is frequently utilised for mobile ad hoc networks (MANETs). OMNeT++ environment offers a modular framework replicating such protocols, and the INET Framework has assist for diverse routing protocols with DSDV.

Here, we will instruct you through these steps to initiate DSDV protocol project using OMNeT++:

Steps to Start DSDV Protocol Projects in OMNeT++

  1. Install OMNeT++ and INET Framework

Make certain that we install the OMNeT++ environment and INET Framework on the system.

Install OMNeT++

  1. Visit OMNeT++ webpage to install it.
  2. Based on the OS, we can adhere to the installation guidance. On Linux, for building, we can be used the terminal and on Windows, we need to utilise Visual Studio.

Install INET Framework

The INET Framework offers wide range of protocols and network modules in OMNeT++. We can make a custom execution of DSDV or we utilise a pre-existing one within INET (via DSDV may not be contained by default).

  1. Replicate or download the INET Framework through GitHub repository.
  2. We adhere to the INET build guidance that typically needs make or cmake.
  1. Understand OMNeT++ Basics

We must know the basics of OMNeT++ framework before beginning a DSDV project:

  • Modules: OMNeT++ simulations have components. Modules can be simple like a router or host or compound (a network of simple modules).
  • NED files: Create the network topology that is how modules are associated.
  • INI files: Make use of .ini files for simulation metrics like module configuration and runtime settings.

We can determine the example projects in the examples directory of OMNeT++ or INET framework to understand how networks are configured.

  1. Find or Implement DSDV in OMNeT++

Since INET framework might not have DSDV by default then some research projects or contributions could provide implementations of DSDV for OMNeT++ environment. We can either utilise existing executions or improve.

Option 1: Use Existing DSDV Implementations

Look for repositories or examples in which DSDV has been executed in OMNeT++. Following is some options:

  • Look in the INET framework: Refer to the INET repository to DSDV (we can confirm the documentation or source files monitoring if it’s previously supported).
  • Third-Party Implementations: A few external sources such as GitHub or research papers could have distributed its DSDV projects in OMNeT++.

Option 2: Implement DSDV Yourself

In the INET framework, we require executing the protocol as DSDV is not available. DSDV is a proactive routing protocol thus execution will want to:

  • Maintain routing tables: Every single node requires sustaining a table including destination sequences.
  • Periodically broadcast updates: Updating neighbors on routing changes.

The execution contains to describe a module or multiple modules within OMNeT++ to utilise NED files. For the DSDV implementation, basic tasks consist of:

  • To execute the DSDV routing algorithm.
  • Modernizing the routing table according to the received data.
  • To propagate routing data regularly to the neighbouring nodes.
  1. Create the Simulation Topology

In OMNeT++, simulating the DSDV we need to delineate a network topology with the support of NED files. Normally, a MANET (Mobile Ad hoc Network) topology will utilise to experiment the DSDV.

Below is an instance of NED file for a basic mobile network including DSDV-enabled nodes:

network DSDVNetwork {

submodules:

node1: MobileHost {

@display(“p=100,100”);

}

node2: MobileHost {

@display(“p=300,100”);

}

node3: MobileHost {

@display(“p=500,100”);

}

connections:

node1.wifi <–> node2.wifi;

node2.wifi <–> node3.wifi;

}

Now, we need to delineate a basic network including 3 mobile nodes such as node1, node2, and node3. We can prolong it by inserting additional nodes and modifying its mobility.

  1. Configure Simulation Parameters

In OMNeT++, simulation metrics are described by using .ini file. For a DSDV simulation, we can:

  • Set the routing tables and DSDV-specific settings.
  • Configure mobility models for mobile nodes such as random walk, or certain mobility scenarios.
  • Fine-tune periodicity of routing updates and other protocol metrics.

Following is a sample configuration file that is omnetpp.ini setting a basic DSDV simulation:

network = DSDVNetwork

sim-time-limit = 100s

**.node*.mobility = “RandomWaypointMobility”

**.node*.mobility.speed = 2m/s

**.node*.mobility.updateInterval = 1s

# DSDV settings (if using an existing implementation or your own)

**.node*.dsvd.routingUpdateInterval = 5s

**.node*.dsvd.routingTableSize = 100

# Output and result collection

*.vector-recording = true

*.scalar-recording = true

Utilise .ini file, we can configure:

  • For the nodes like RandomWaypointMobility for random movement, we need to configure Mobility model.
  • DSDV parameters such as update intervals and routing table size.
  • Output settings to log statistics and envision the outcomes.
  1. Run the Simulation

After implementing the topology and configuration then we can execute the simulation:

  1. Compile the project to utilize build system of OMNeT++. For instance, make or from the OMNeT++ IDE.
  2. Introduce the simulation either using OMNeT++ IDE or through the command line.
  3. Analyze the results: OMNeT++ environment offers numerous analysis tools for examining the simulation result like scalar results, vector files, and logs, which can be utilised to monitor the changes of routing table, packet delivery rates, and other performance parameters.
  1. Analyze and Visualize the Results

OMNeT++ offers external tools for detailed analysis:

  • Vector & Scalar Recording: Make use of vector and scalar recording within the .ini file logging crucial performance parameters such as packet delivery ratio, routing updates, and latency.
  • Tkenv: Envision the network topology, routing updates, and node movements to utilize the Tkenv graphical interface.

For instance, we can envision the routing table changes over time or examine the network throughput.

  1. Extend and Experiment

When simple DSDV simulation is functioning then we can test with diverse network scenarios to contain:

  • Various mobility models such as random walk, Gauss-Markov, and so on.
  • Network density: To change the volume of nodes within the network.
  • Node failure or link breakage: Mimic network failures and then monitor how DSDV responds.

Also, we can prolong the protocol by executing further aspects such as:

  • Route optimization or route aggregation.
  • Integration including other protocols like TCP, UDP, or other routing protocols such as AODV or OLSR.

We can begin replicating the DSDV protocol projects using OMNeT++ by following these steps and we will expand it to examine more functionalities of this project in upcoming guide.
