The graphical user interface
Remote OMNeT++ v2.0
Client
Usage
• Login to the remote servers (Processing Host and Data Warehouse)
• Transfer the local files you wish to store to the Data Warehouse
• Transfer the necessary files to the Processing Host
• Compile the simulation on the Processing Host
• Execute the simulation
• The results are transferred to the Data Warehouse
• View the results or download them to the local computer
Remote OMNeT++ v2.0
Client
Usage
• You can disconnect after starting the simulation
• You can always connect to the servers later to monitor the progress
• You can watch monitored parameters as the simulation is running
• Your files are kept on the Data Warehouse where you can access them
• You are identified by a username and a password to protect data

Possibilities
Kinds of simulation supported
• Ability to execute multiple simulations concurrently
• Run a simulation with different parameters concurrently
• Run a simulation in parallel using PVM and cluster technology
Remote OMNeT++ v2.0
Possibilities
Data analysis
• Results and models are stored in a Data Warehouse
• Data can be analyzed on the local computer
• Client application can be expanded to add new analysis tools
Remote OMNeT++ v2.0
Future
New possibilities
• The user should be able to develop new models in a graphical editor
• Models can be constructed from pre-created primitives
• Support for developing parallel models
