LDACS-GeoOpt-Simulator is a paper-specific OMNeT++ simulator repository for evaluating GeoOpt routing in sparse LDACS air-to-air networks. It is focused on the French airspace equipage-fraction scenario used for the GeoOpt study.

The included scenario and scripts are prepared to compare:

• Greedy-1
• GPSR
• GeoOpt
• Dijkstra: Implements the Dijkstra's shortest path routing algorithm which serves as a baseline.

• scenarios/ — NED network and OMNeT++ configuration files
• scenarios/results/ — Makefile, plotting environment, and result-processing scripts

Clone the repository and run:

git clone https://github.com/ComNetsHH/LDACS-GeoOpt-Simulator
cd LDACS-GeoOpt-Simulator
bash install.sh

The installation prepares the workspace under omnetpp-5.6.2/workspace/.

It downloads or clones the required simulator dependencies, including:

• OMNeT++ 5.6.2
• INET 4.2.5
• LDACS-Abstract-Radio
• LDACS-Abstract-TDMA-MAC
• LDACS-Greedy-K-Hop-Routing
• LDACS-Dijkstra
• LDACS-GPSR-Routing
• LDACS-GeoOpt-Routing

cd scenarios/results
make build-release
make run-paper-simulations-local
make generate-all-equipageFraction-csv
make plot-equipage-fraction-metrics

cd scenarios/results
make run-all-simulations-from-hpc-equipageFraction

• The workspace root used by the Makefile and shell helpers is ../../omnetpp-5.6.2/workspace/.
• The GeoOpt routing implementation is intended to live in its own routing repository.
• The plotting scripts assume OMNeT++ result files are exported into scenarios/results/simresults/.
