ScOSA SpaceWire Simulator

This project is for creating OMNeT++ simulations of SpaceWire network based on a system description in JSON (exported from VirSat ScOSA). The main author is Alan Aguilar Jaramillo.

Installation

The following procedure has only been tested for Windows 10. However, it should apply to any system that can support OMNeT++.

  • Download and Install OMNeT++ in your system (see OMNeT++ Installation Guide https://doc.omnetpp.org/omnetpp/InstallGuide.pdf).
  • Open OMNeT++ and set the Workspace directory to the desired folder.
  • Clone this simulator and import it into ONMET++ Workspace.
  • Validate the install by opening scosa-simulator/simulations/omnet.ini file in OMNeT++ and pressing the green arrow in the menu bar to run the simulation.

Set-up and Running a Simulation

The simulator is designed to read JSON files and recreate the network as described in them. VirSat ScOSA allows for the user to output all possible configurations to a user-defined directory. To recreate these networks from said files, the user must follow the next procedure:

  • Export network configuration JSON files from VirSat ScOSA.
  • Ensure that the files follow the naming scheme config<CONFIGURATION NUMBER>.json.
  • Place folder containing the exported JSON files into the scosa-simulator/input directory.
  • Set simulation parameters to match scenario (see user guide document).
  • Run network simulation in OMNeT++.

Output processing

We added some Python scripts in output for analyzing and visualizing simulation results. The code runs on Python 3.8 and uses the following libraries:

  • pandas (BSD 3-Clause License)
  • numpy (BSD 3-Clause License)
  • matplotlib (PSF-based license)
