To simulate Associative-Based Routing (ABR) protocol projects using OMNeT++, we can follow these general steps.For best simulation guidance stay in touch with phdprime.com we do assure you with best outcomes:
Steps to Simulate ABR Protocol Projects in OMNeT++
- Install OMNeT++
Make sure that OMNeT++ is appropriately installed on the system. We can download and install OMNeT++ from the official OMNeT++ website. Furthermore, install INET Framework, as it offers support for network simulations.
- Set Up the INET Framework
Since ABR contains mobile ad hoc networks (MANETs), the INET framework will be needed. INET supports numerous wireless protocols and network models that can be changed or expanded to execute ABR.
- We download INET from the OMNeT++ package manager or manually from the INET repository.
- Configure INET by compiling it in OMNeT++.
- Understand ABR (Associative-Based Routing) Protocol
The ABR protocol is created for mobile ad hoc networks (MANETs) and operates by establishing routes according to the “associativity” of nodes with each other. It identifies stable routes via associativity ticks.
Key aspects to implement:
- Associativity-based metric: Nodes with long associativity ticks are deliberated to be more stable.
- Route discovery and maintenance: Design mechanisms for introducing and conserving the stable routes in dynamic network topologies.
- Route repair: Manage broken routes because of the node mobility.
- Create a Custom ABR Protocol
We will want to execute the ABR protocol as a new module within OMNeT++. Here’s how:
- Create a new protocol module: Expand an existing routing protocol (like AODV) or make a new one from scratch. In the src directory of INET, traverse to the networklayer section and then describe a new folder for ABR.
- Define ABR behaviors: Write custom C++ code to describe the associativity metric, route discovery, and repair algorithms. It can be done by changing or making classes, which manage packet forwarding, route tables, and route metrics.
- Modify OMNeT++ NED Files
Change the NED files (Network Description files) to contain the ABR protocol within the network configuration. Describe how mobile nodes are communicate using the ABR routing protocol then configure the simulation environment with wireless interfaces.
For example, in the NED file:
network ABR_Network
{
submodules:
mobileHost[10]: ABRNode;
…
}
- Create a Simulation Configuration File
We will require to configure a simulation configuration in the omnetpp.ini file. Describe the number of nodes, simulation time, mobility patterns, and ABR-specific settings.
Example snippet from omnetpp.ini:
[General]
network = ABR_Network
**.mobilityType = “MassMobility”
**.routingProtocol = “ABR”
**.numHosts = 10
sim-time-limit = 1000s
- Test and Validate
- We run the simulation and monitor how ABR implementation behaves.
- Utilize Mobility models in INET (such as random waypoint or Gauss-Markov mobility) to mimic node movement.
- Collect parameters such as packet delivery ratio, average delay, and overhead to examine the performance of the ABR protocol in numerous scenarios.
- Visualize the Results
OMNeT++ offers tools to envision the network and monitor packet flow. We can be examined simulation outcomes utilizing OMNeT++’s vector and scalar plotting tools or transfer the data for further analysis.
- Optimization and Documentation
Refine the protocol according to the simulation outcomes. Create adjustments to the associativity algorithm or route maintenance logic as required. Make certain that code is well-documented for future reference.

As explained above is a simplified process on how to simulate the ABR Protocol projects and how to visualize its outcomes using OMNeT++ tool. If you have any doubts on this process, we will definitely clear it.
