The P2P Simulation Framework

OverSim is an open-source overlay network simulation framework for the ​OMNeT++/OMNEST simulation environment. The peer-to-peer simulator contains several models for structured (e.g. Chord, Kademlia, Pastry) and unstructured (e.g. GIA) P2P protocols.

OverSim is developed at the ​Institute of Telematics (research group Prof. Zitterbart), Universität Karlsruhe (TH) within the scope of the ​ScaleNet project funded by the ​German Federal Ministry of Education and Research. The simulator is actively developed and open to contributions. If you have any questions regarding OverSim, please send an email to the MailingList.
