Objective

Use OEDL script to execute transmit and receive benchmark scripts on the grid.

Hardware / Software Resources utilized

  1. Two grid nodes with USRPs.
  2. baseline-gnu-12-04-32bit.ndz: disk image loaded onto nodes. This image has all the prerequisite software to configure the USRPs.
  3. Orbit's Arbitrary Waveform Injection System: used to inject noise or simple signal into RF environment. ​More information of this generator can be found here.
  4. Packet server: This is server that resides on the grid console and used by a transmitting node to send data packets over the air via USRP.
  5. dc.rb: this is the ODEL experiment script to manage GNURadio code, interference service and packet server and execute the hurdle (i.e. run the transmit and receive scripts).

Set up

  • After logging into grid console, make sure all nodes are turned off (in the example below, turn off all the nodes in the grid): 
    username@console.grid:~$ omf tell -a offh -t system:topo:all
  • Verify state of node before continuing. Make sure nodes are in the POWEROFF state. 
    username@console.grid:~$ omf stat
  • Image nodes (this will image all nodes with USRPs with SBX daughtercards): 
    username@console.grid:~$ omf load -i baseline-gnu-12-04-32bit.ndz -t node1-1.grid.orbit-lab.org,node20-20.grid.orbit-lab.org -r 20
  • After nodes are imaged, verify that nodes are in POWEROFF state. Otherwise issue the following to turn them off for a reboot 
    username@console.grid:~$ omf tell -a offh -t node1-1.grid.orbit-lab.org,node20-20.grid.orbit-lab.org
  • Turn nodes back on and verify they are in POWERON state 
    username@console.grid:~$ omf tell -a on -t node1-1.grid.orbit-lab.org,node20-20.grid.orbit-lab.org
  • Download the OEDL experiment script to your local directory. 
    username@console.grid:~/UHD$ wget http://www.orbit-lab.org/raw-attachment/wiki/DSC/dc_trial1/dc.rb

Run the experiment script

  • Type to following command to run the experiment. This will start the packet server, configure and start the interference generator and finally kick off the transmit and receive benchmark scripts within the nodes. 
    username@console.grid:~/UHD$ omf exec dc.rb
  • The output should look similar to the following: 
    username@console.grid:~# omf exec dc.rb
