The code has been fully updated to the OMNeT++ 6.0 and INET 4.4 versions. The OS3 project has also been updated, so ensure that this is also used. A full description of the installation is within the README file. The UnitDiskRadio model previously used is now omitted from the primary models in favour of a new PPP implementation. The igraph library is used (see igraph project in Avian688/igraph) which requires specific dependencies outlined by igraph install guides online and the README file. The new implementation works by creating an igraph topology every x seconds which can save a given constellation for a time period. This will speed-up experiments by allowing you to load a configuration for a LEO constellation, removing the need to constantly perform routing every time the simulations are run. Do not hesitate to ask questions if you have any issues settings this up, there are quite a few dependencies now which I will make easier to install in the future!
Best,
