Simple radio example with GNURADIO benchmark scripts

Description

This example will utilize an OEDL script to execute packet transfers over a radio link created using GNU Radio. This is will involve running a GNU Radio benchmark script two nodes each with a USRP2.

Hardware / Software Resources utilized

1. Grid nodes with a USRP2 connect via Ethernet.
2. baseline-12-04-gnu.ndz: disk image loaded onto nodes. This image has all the precompiled - software required to configure the USRP2s and all the required GNU Radio software libraries. The USRP2's interface with the node is already configured.
3. GNU Radio - software library to create SDR. Click here for ​additional info.
4. USRP2 - hardware platform for SDR.

Set up

• To get started first make a reservation on the ​Orbit Scheduler for using the Grid.

• After logging into grid console, make sure all nodes are turned off

  nilanjan@console.grid:~$ omf tell -a offh -t system:topo:all
  

• Verify state of node before continuing. Make sure all nodes are in the POWEROFF state.

  nilanjan@console.grid:~$ omf stat
  

• Image nodes. Two (2) are required to run - check ​inventory status to find nodes with 2 similar USRP2s. In this examples we'll use node1-1 and node1-2.

  nilanjan@console.grid:~$ omf load -i baseline-12-04-gnu.ndz -t node1-1,node1-2
  

• Turn nodes back on and verify they are in POWERON state

  nilanjan@console.grid:~$ omf tell -a on -t system:topo:imaged
