GloMoSim (Global Mobile Information Systems Simulation Library) is a simulation environment based on the Parsec engine using its parallel discrete-event simulation capability. It is freely available for academic use, but its development has been freezed with version 2.03. Newer versions are available as a commercial product referred to as QualNet. However, GloMoSim is still widely used in academic research.
The GloMoSim communication stack is based on a layered approach, providing most used protocols:
| Layer | Models |
|---|---|
| Physical (Radio Propagation) | Free space, Two-Ray |
| Data Link (MAC) | CSMA, MACA, TSMA, 802.11 |
| Network (Routing) | Bellman-Ford, FSR, OSPF, DSR, WRP, LAR, AODV |
| Transport | TCP, UDP |
| Application | Telnet, FTP |
