$ sudo pip install pandas networkx

Run

$ python nwGen.py -f <inputfile> -n <nodes> -d <degree>

Or you can edit your configuration in trafficPattern.py and simply run

$ python nwGen.py

Source Files

nwGen.py

• This is the main program.

algorithm.py

• This includes various required algorithms in the main program.

trafficPattern.py

• This helps to produce classical traffic patterns.

Output

The topology information is stored in the output/ folder. Each line follows the format as follows.
