| | 3 | == Getting Started with COSMOS SDR Resources == |
| | 4 | |
| | 5 | === Description === |
| | 6 | In this tutorial we'll demonstrate how to run a basic wireless experiment using software defined radios in the COSMOS testbed. Two COSMOS nodes will be used: one to transmit a signal, and the other to receive it. |
| | 7 | |
| | 8 | === Prerequisites === |
| | 9 | All tutorials on the COSMOS wiki assume that you have already created a user account through [https://www.orbit-lab.org/userManagement/register the new user registration form]. |
| | 10 | |
| | 11 | In order to access the test bed, create a reservation on [https://wiki.cosmos-lab.org/cPanel/controlPanel/start the online scheduler] and have it approved by the reservation service. Access to the resources are granted after the reservation is confirmed. Please see the page describing [wiki:CosmosOverview/Workflow the COSMOS work flow page] for more information. |
| | 12 | |
| | 13 | === Resources required === |
| | 14 | For this example we used two USRP 2974 SDRs on [wiki:Architecture/Domains/cosmos_sb1 sandbox 1]. |
| | 15 | |
| | 16 | === Tutorial Setup === |
| | 17 | Follow the steps below to gain access to this console and set up your node with an appropriate image. |
| | 18 | 1. [GettingStarted#MakeaReservation Create a resource reservation] for sandbox 1. |
| | 19 | 2. Once reservation is approved, [wiki:GettingStarted#LogintoyourReservation login into the console] using ssh. Since you are using sandbox 1, you will ssh to |
| | 20 | {{{#!shell |
| | 21 | YOUR_USERNAME@console.sb1.cosmos-lab.org |
| | 22 | }}} |
| | 23 | 3. Use OMF commands to [GettingStarted#ControlResourceswithOMF load the baseline-uhd.sdr image] on your resources. |
| | 24 | {{{#!shell |
| | 25 | omf load -i baseline-uhd.ndz -t sdr2-s1-lg1,sdr2-md1 |
| | 26 | }}} |
| | 27 | 1. Once the nodes are successfully imaged, turn them on and check the status |
| | 28 | {{{#!shell |
| | 29 | omf tell -a on -t sdr2-s1-lg1,sdr2-md1 |
| | 30 | }}} |
| | 31 | {{{#!shell |
| | 32 | omf stat -t sdr2-s1-lg1,sdr2-md1 |
| | 33 | }}} |
| | 34 | 1. After waiting for the nodes to power up and boot, you will be able to ssh to them from the console: |
| | 35 | {{{#!shell |
| | 36 | ssh root@sdr2-s1-lg1 |
| | 37 | }}} |
| | 38 | NOTE: for some nodes, such as the server machines, it can take several minutes for a node to finish the booting process. This is normal, and you'll have to wait until the nodes is fully booted before you can ssh to it. |
