Optimized Geographic Greedy Routing

OMNeT++/INET routing module and simulation setup for an optimized geographic greedy routing approach with beacon-based neighbor awareness, optional k-hop neighbor selection, and load-balancing support.

Repository structure

• src/ — routing implementation, message definitions, and NED module
• simulations/ — simulation networks and configuration files
• NATselB_2019A2G_data/ — scenario and ground-station input data

Main components

• OptimizedGeographicGreedyRouting.cc/.h — routing logic
• PositionTableModified.cc/.h — neighbor position and metadata tables
• OptimizedGeographicGreedyRouting.msg — OMNeT++ message definitions
• OptimizedGeographicGreedyRouting.ned — routing module parameters
• simulations/ch6_scenarioFR_equipage_fraction.ini — example simulation configuration

Requirements

This project references external OMNeT++/INET-based modules that are not bundled in this repository, including custom LDACS and traffic application components. Make sure the required dependencies are available in your OMNeT++ workspace and that their paths/imports match your local setup.

Running a simulation

Typical workflow inside the OMNeT++ IDE:

1. Import the project.
2. Make sure all referenced dependencies are present in the same workspace.
3. Build the project.
4. Run a configuration from simulations/ch6_scenarioFR_equipage_fraction.ini.

Notes for publishing

• The source tree contains file headers from existing GPL/LGPL-licensed code.
• Before publishing publicly, review and add a repository-level LICENSE file that matches your intended redistribution terms and all upstream obligations.
• Review dependency licenses as well if you plan to distribute a complete workspace.
