Topology 4: Concurrent Traffic Sessions (MAC Fairness)

Goal

This represents a typical scenario with multiple indepdent traffic session sharing a same 802.11 channel.

Steps

In order to achieve this, the following steps are needed

• run the nodehandler script in the grid: ./nodehandler macfair
• run the post-process perl script: ./dbprocess.pl
• view the EPS file named "gnuplot_graph1.ps", which contains throughput comparison plots for each flow.

Scripts

• The nodehandler script (RUBY) to run this experiment:
  • ​4flows with Master/managed settings
• The ​perl script to postprocess database and plot the results in EPS file.
• The gnuplot configuration file

Sample Results

We plot the (Throughput, RSSI, PHY rate) for each individual session using the experiment script provided above.
