This simulation environment of Contact Graph Routing that uses the QualNet network simulator leverages the previously developed space communication models. This software models the Contact Graph Routing (CGR) system proposed for future NASA missions and used in DINETl and DINET2 experiments. It runs inside the QualNet network simulator. This protocol model can assist NASA network designers who wish to use Delay Tolerant Networking protocols with Contact Graph Routing.
