Creating and Loading a Disk Image

To prepare this experiment, we loaded a baseline image onto a node at NYU Poly.

Try it yourself another time: To load a baseline image onto a node, e.g. node9 at NYU Poly, run
omf load -i baseline.ndz -t omf.witest.node9


Then we installed all the applications on the node and saved the disk image.

Try it yourself another time: To save a disk image from a node, e.g. node9 at NYU Poly, run
omf save -n omf.witest.node9


When the image saving process concluded, it reported that the disk image had been saved and gave the name of the image. Now, when we want to run this experiment, we can load this disk image onto the nodes:

omf load -i gec16-coop.ndz -t omf.witest.node5,omf.witest.node8,omf.witest.node13

Clearing Experiment Settings

In addition to loading a fresh disk image, additional steps must be taken to restore the wireless environment to its default state. These commands are run from the console on witest to reset all of the base station settings:

wget -qO- "http://wimaxrf:5052/wimaxrf/bs/default"
wget -qO- "http://wimaxrf:5052/wimaxrf/bs/restart"
