Our IEEE 802.11a/g/p transceiver comes with a complete simulation tool chain and two example simulation studies;
one to study the performance of the encoding schemes over an AWGN channel, and one to study the sensitivity of the frame detection algorithm.

The whole process is orchestrated by a Makefile, which has several advantages:
- Simulations can be run in parallel
- Canceled or failed runs are repeated automatically
- No need for manual dependency tracking
The work flow is straightforward and comprises:
- Create a non-GUI flow graph that can be configured through command line arguments (cf. Parameter block).
The flow graph logs its output to a normal file or a PCAP frame dump, dependent on what aspect of the system is studied.
To ease evaluation of the results, the parameters are part of the output file name.
- We configure the parameters and repetitions in the Makefile, which runs the flow graph with all parameter combinations.
- Once all simulations runs are completed, a parse script will iterate through all output files to extract relevant information (like the number of received frames).
The results are stored in a CSV file.
- The resulting CSV file is processed with a Python script that visualizes the results in a graph.
Once everything is setup, the whole process can be started with
make -j 5, where the
-j option defines the number of parallel simulation runs.
Starting the Makefiles of the example simulations included with the module will produce the following graphs.
