= 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
 * The corner node (1,2) is selected as the AP 
 * Select the set of nodes on the grid as required (clients)
 * Disable autorate adaptation in the card
 * Set the PHY rates to fixed rates based on the distribution required by the experimenter

== Scripts ==
The script to run this experiment can be found [http://www.orbit-lab.org/attachment/wiki/Internal/Mapping/Topologies/Topo2/macfair.rb here]

== Sample Results ==
We plot the throughput for each individual session using the experiment script provided above.
