Automatic Repeat reQuest

[hellozeyu]

Hey, I am now working on a project that comparing the efficiency of three ARQs (stop-and -wait, go-back-N and selective repeat) under different conditions. Now I have four usrp2 and PXI. Is there any vi that I can take as an example since I got nothing useful after I searched ARQ at ni.com. Thank you!

Hello,

I don't know of any pre-written LabVIEW example code specifically for ARQ. My understanding is that ARQ would be a feature of a MAC layer sitting on top of a PHY layer implementation. What protocol or PHY are you working with? There may be at least a starting point that can get you from RF waveforms to bits. It sounds like you're planning to implement two-way communication.

My teacher didn't mention the specific PHY layer that we should use. In that case, 802.11, 802.15.4 or so would all be OK.  When I was working on NS2, the example code would include not only PHY or MAC layer's name but ARQ mode as well. To implement it on hardware, I start learing  labview and usrp. The most common condition would be one node sending message and another receiving it.
