'''[wiki:GEC16Agenda/WiMAX-Tutorial/Coop/05 Previous]''' == Run the experiment == Ready to run the experiment? First turn the nodes on, since they'll still be off after being imaged: {{{ omf tell -a on -t omf.witest.node4,omf.witest.node6,omf.witest.node13 }}} [[br]] Then run: {{{ omf exec wmxtutor-coop.rb }}} [[br]] Once the experiment has concluded, note its Experiment ID and push the results to a "coop" directory in iRODS using this ID: {{{iarchive -e expID -c coop}}} [[br]] To view your experiment results, visit the iRODS web browser at [http://witestlab.poly.edu/irods/web]. Use: * '''Host''': emmy9.casa.umass.edu * '''Port''': 1247 * '''Zone''': geniRenci [[br]] Click on the 'sq3' file generated by your experiment and click 'Plot' to create simple plots of measurements stored by OML. For example, try these: * In the table 'wxmstat_status_link', plot 'oml_seq' on x-axis, 'cinr' on y-axis, and group by 'oml_sender_id' to see how the WiMAX link quality varies across the different nodes and over the duration of the experiment. * In the table 'coopshim_req', plot 'oml_seq' on the x-axis, 'total' on the y-axis, and group by 'oml_sender_id.' This will show you how many packets were requested by each node in the experiment for cooperative recovery from peers. * Plot the same for the 'coopshim_recv' to see how how many packets were recovered by each node from peers. * In the table 'iperf_UDP_Rich_Info', plot 'Begin_interval' on the x-axis and 'Bandwidth' on the y-axis and group by 'oml_sender_id' to see the received data rate (including recovered data) observed at each node over the duration of the experiment. You can also download the sq3 file and explore the data using an SQLite browser such as [https://addons.mozilla.org/en-US/firefox/addon/sqlite-manager/ this Firefox plugin].
