    257257 2. ''node.addApplication'' connects the previously defined ''iperf'' application to the node(s). ''iperf'' is configured as a client connection to the specified ip address.
    258258 3. The wireless card properties are set using with the ''node.net.w0'' parameters. Note that we set ''node.net.w0.mode'' to ''managed'' to configure the wireless card as client. Other relevant parameters are also set here as well. Since we can have multiple nodes we specify ''node.net.w0.ip'' with the last byte of the IP address as %index%. In this way each node will have a unique address.

     260* At the end of the script once all the nodes are at the same point and all applications have been initialized, an event is triggered to continue and execute the remaining steps. The 10 second delay before the call to ''startApplications'', this allows time for the clients to establish a wifi connection with the access point before continuing. Iperf is started on all the nodes, execution of experiment script is delayed again giving time to collect experiment data. Finally all applications are stopped and the experiment exits out.

     274=== Executing the Experiment Script ===
     275An overview on running experiment scripts on the orbit testbed can be found on the [wiki:Documentation/CGettingStarted Getting Started Page].
     276In order to run this experiment script, load ''baseline.ndz'' image on nodes with wifi cards. Check the ''Status Page' on the [https://www.orbit-lab.org/cPanel/controlPanel/start Control Panel] to select any particular type of wifi card.
     277{{{
     278nilanjan@console.grid:~/EXP$ omf load -i baseline-wpa.ndz -t node15-1,node16-1,node17-1,node19-1,node20-1
     279}}}
     280
     281After the nodes have finished imaging, turn the nodes on. The topology used here is ''system:topo:imaged'' which selected the prior set of node that were successfully imaged.
     282{{{
     283nilanjan@console.grid:~/EXP$ omf tell -a on -t system:topo:imaged
     284}}}
     285
     286To run this experiment with 2 clients nodes:
     287{{{
     288nilanjan@console.grid:~/EXP$ omf exec test:exp:tutorial:wifi-ap-iperf.rb -- --accesspoint node15-1 --client node16-1,node17-1 --duration 60
     289}}}
     290
     291The output of this script should be similar to the following:
