OMNeT++ 2.3

OMNeT++ is a discrete event simulation environment that supports a variety of simulation models including queuing, network protocols, and mobility. Developed by Andras Varga, this open-source framework is widely used in the research and academic communities for modeling complex communication systems. The tool provides a modular architecture that allows users to extend its capabilities through the creation of custom simulation models and frameworks.

One of the key features of OMNeT++ is its extensive library of pre-built models and components, which helps researchers quickly set up simulations for their specific needs. Users can leverage these existing modules or develop new ones from scratch using C++ or a high-level language like NED. This flexibility makes it ideal for simulating a wide range of systems, from small-scale networks to large-scale distributed environments.

OMNeT++ also offers support for parallel simulation, enabling users to take advantage of multi-core processors to speed up simulation runtime. In addition, the tool provides multiple output formats for data analysis and visualization, such as scalar output for basic statistics and vector output for plotting graphs.

• Modular Architecture: Allows users to customize and extend the framework with their own simulation models.
• Extensive Library: Offers a wide range of pre-built components for quick simulation setup.
• Support for Parallel Simulation: Utilizes multi-core processors to accelerate simulation runtime.
• Data Analysis and Visualization: Provides output formats for easy interpretation of simulation results.

OMNeT++ is a powerful tool for researchers and academics seeking to model and simulate complex communication systems. With its flexible architecture, extensive library, and support for parallel simulation, it remains a popular choice for studying the behavior and performance of networks, protocols, and other communication technologies.
