• Oversim: OverSim is an OMNeT++-based open-source simulation framework for overlay and peer-to-peer networks, developed at the Institute of Telematics, University of Karlsruhe (TH), German. The simulator contains several models for structured (e.g. Chord, Kademlia, Pastry) and unstructured (e.g. GIA) peer-to-peer protocols. An example implementation of the framework is an implementation of a peer-to-peer SIP communications network. OverSim has a flexible underlying network scheme, which on the one hand provides a fully configurable network topology with realistic bandwidths, packet delays, and packet losses (INETUnderlay), and on the other hand a fast and simple alternative model for high simulation performance (SimpleUnderlay).

  • OMNET++: OMNeT++ is a component-based, modular and open-architecture discrete event network simulator. The most common use of OMNeT++ is the simulation of computer networks, but it is also used for queuing network simulations, and other areas as well. OMNeT++ is popular in academia for its extensibility (due to its open source model) and plentiful online documentation. OMNeT++ represents a framework approach. Instead of containing explicit and hardwired support for computer networks or other areas, it provides an infrastructure for writing such simulations. Specific application areas are catered by various simulation models and frameworks, most of them open source. These models are developed completely independently of OMNeT++, and follow their own release cycles.
