49 | | Basically, nodeHandler is a comprehensive tool to control the whole experiment in Orbit-testbed, including power on/off nodes, setup/break wire/wireless links. As OTG software can be used to test a link only after the link is eatablished. It is not a bad idea to also use "nodehandler" to give command-line options and run-time options for OTG/OTR program. Also, with this, users do not need to SSH to everynode and run the OTR program one by one manually. |
| 49 | Basically, NodeHandler is a comprehensive tool to control the whole experiment in Orbit Testbed, including the functuons to power on/off nodes, setup/break wired/wireless links. As OTG software can be used to test a link only after the link is eatablished, it is not a bad idea to use "nodehandler" to give command-line and run-time options for OTG/OTR program too. Therefore, the nodehandler script will include all necessary information to start, stop and control OTG programs. Users will no longer need to input command line arguments manually. What's more, with this, users do not need to SSH to everynode and run the OTG program one by one manually if an experiment involves a large number of nodes. |
