Hi all! I'm starting to work on a project and first of all would like to know if it'd be possible or what recommendations anyone has on it.
Basically what I want to accomplish is the following: Host A: USRPv1 + RFX2400 Host B: USRPV1 + RFX2400 Both hosts would: 1) Always scan for the wireless spectrum (2.402 - 2.482 GHz). 2) Find the best frequency to transmit based on signal-to-noise ratio. 3) Build a Local Database table with the signal-to-noise ratio on each frequency as well as the ID of each user. 4) Begin advertising its ID on the best frequency available at the time and only change that frequency if some signal-to-noise threshold is reached or if needing to find a peer on another frequency. 5) Begin communication with desired peer through a tunnel interface. (Not sure if I'd need 1 (one) or 2 (two) RFX2400 on each USRPv1 since spectrum sensing would be up always. Any ideas?) 6) Share next best frequencies with neighbor. 7) Update the Database Table. 8) Compare Database Tables to find the best common frequency. 9) Tell next peer which frequency to change to (3-way handshake) 10) Back to 6 Does anyone have any ideas if this can work, and some clues of how to? I have found the following thread which is kind of similar: Tunnel and sense in the same USRP device http://old.nabble.com/Tunnel-and-sense-in-the-same-USRP-device-td24729726.html#a24729726 Of course I'd need to establish communication before and scan the spectrum and that's what the above thread is about. I would need to accomplish that plus more things. Any ideas, thoughts, suggestions is much appreciated. Thanks a lot!!
