This repository is part of the L-Band Digital Aeronautical Communications System (LDACS) Air-Air (A/A) mode simulator that implements the proposed Medium Access Control (MAC) protocol "Multi Channel Self-Organized TDMA (MCSOTDMA)".

This repository implements a trace-based application for OMNeT++ that allows trace-file-based application definitions. For example, it can realize realistic Air Traffic Control (ATC) communications based on trace files that describe these.

UdpTraceBasedApp

OMNeT++ Trace-Based Data Traffic Application extends the INET's UdpBasicApp by using a trace file to trigger the packet transmission. The file is a plain text file, where every line describes the trigger time of one packet, e.g.,

• t₁
• t₂
• ...
• t_last

The UdpTraceBasedApp application send the first packet at t₁ and the last packet at t_last.

Getting Started

1. Please download inet-4.2.5 for OMNeT++ 5.6.2 and import it into the simulator.
2. Please clone this repo UdpTraceBasedApp and import it into OMNet++. To build it you need to do the following steps:
   1. inet must be set as a project reference. This is done by right-clicking on the UdpTraceBasedApp project in the Project Explorer and navigate to Properties-> Project References -> Select inet -> Apply and Close
   2. Ensure the build modes of this project and inet are identical (both release or both debug): This is done by right-clicking on each project in the Project Explorer and navigating to Build Configuration -> Set Active -> <mode>
   3. The include paths from INET must be added to this project such that you can write classes in your project which inherit inet classes. For that, you need to right-click on the UdpTraceBasedApp in the Project Explorer and navigate to Properties -> OMNeT++ -> Makemake, select the src folder in the list and then click "Options" in the right panel.
   4. Go to the Target tab and make sure that Shared library ... is checked.
   5. Now go to the Compile tab and make sure all checkboxes are checked.
   6. Move to the Link tab and make sure that the Link with libraries exported from... checkbox is checked.
   7. Finally, Apply and Close and you should be able to build the UdpTraceBasedApp project without errors as a project that reference the INET project.
