When I run my experiment, the wireless channels do not seem to change as I specified, i.e. they are fixed.
Occasionally the controller that connects emucontrol-1 to the emulator hardware crashes. You can verify whether it is working correctly, by executing
If the ping fails, the controller is down and you should send mail to email@example.com so we can reset it. If you get a ping response the controller is working correctly and your problem lies elsewhere. You should check your script or code to make sure you are controlling the channels correctly.
When I run emulatorDaemon on emucontrol-1.ece.cmu.edu, why does it ask for passphrase.
If you are asked to provide passphrase, it means your ssl certificate is not set up correctly. Follow the instructions on the Setting up Account page carefully.
Did you run "startDaemon" for nodes that is remotely controled by emucontrol-1?
Use "sudo [command]". A few commands require root access to be executed.
We suggest to use FC6w-EMU for dell laptops. If you are using USRP, "gnuradio1" is the recommended desk image.
No. The channels between these nodes (in the same group) have multiple-path (up to 3).
Group 1: pcemu107 and pcemu108
Group 2: pecmu113, pcemu114, and pcemu115
Yes. To use USRP, a special command need to be sent to the node, so that it connects USRP instead of the wireless interface to the Emulator Hardware. If you are interested, please email firstname.lastname@example.org for details.
