Welcome to the OMNeT++ Community!

OMNeT++ is an extensible, modular, component-based C++ simulation library and framework, primarily for building network simulators. "Network" is meant in a broader sense that includes wired and wireless communication networks, on-chip networks, queueing networks, and so on. Domain-specific functionality such as support for sensor networks, wireless ad-hoc networks, Internet protocols, performance modeling, photonic networks, etc., is provided by model frameworks, developed as independent projects. OMNeT++ offers an Eclipse-based IDE, a graphical runtime environment, and a host of other tools. There are extensions for real-time simulation, network emulation, alternative programming languages (Java, C#), database integration, SystemC integration, and several other functions.

OMNeT++ is free for academic and non-profit use, and it is a widely used platform in the global scientific community. Commercial users must obtain a license from More...

CVS Model Repository
Tuesday, 21 November 2000 21:32
OMNeT++ CVS Model Repository was set up at the University of Karlsruhe. This site offers simulation models for OMNeT++. If you are developing models yourself, this is a place where you can share your code with others. If you find a simulation model on this server that satisfies your needs, you are encouraged to contribute to its further development.
Updated projects page
Tuesday, 21 November 2000 21:26
Updated the Current projects page; also added OMNeT++ development roadmap.
