OMNeT++

OMNeT++: Simulation library for creating network simulators.

Simulation library for creating network simulators.

OMNeT++ is built as an extensible, modular and component-based C++ simulation library and framework. It is primarily designed 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.

NOTE: OMNeT++ is free for academic and non-profit use.
