To do this, we make some changes to the experiment script (the modified version is saved as '''wmxtutor-streamload2.rb'''). 33 34 We add some properties to the beginning of his experiment: 33 35 34 36 {{{ … … 37 39 }}} 38 40 39 and change sthe sequence of events in the experiment to look like this:41 and change the sequence of events in the experiment to look like this: 40 42 41 43 {{{ … … 86 88 * Plot table 'wmxstat_status' with 'oml_seq' on the x-axis, 'cinr' on the y-axis, and group by 'oml_sender_id'. This will show you the WiMAX link quality as measured at each node for the duration of the experiment. 87 89 90 The results may look something like this: 91 || [[Image(wmxstat-sl-dynamic.png, 350)]][[BR]] WiMAX link status||[[Image(play-sl-dynamic.png,350)]][[BR]]Layers played, per segment || 92 88 93 89 94 Note how the WiMAX link quality changes over the duration of the experiment. Also, note that the number of layers in the video playback changes with the link quality.
