What is default Primary user activity model in "cognitive" folder ?

cai · 05-07-2017, 07:44 PM

After i've applied CRCN patch, cognitive folder is created. Inside that folder is PUmodel.cc and PUmodel.h and many more. I've read journals and there are many PU activity models such as Markov chain and On/off exponential distribution. So, what PU model is used in the CRCN patch (in pumodel.cc)? thank you

This sounds like a highly specialized topic.

It might help were to provide some background to jargon you are using. What distro/version are you using, what is a "CRCN patch," what exactly did it patch and what are you trying to accomplish. Frankly, I for one would rather not go blindly off on a web search without context that you could easily provide.

I'm sorry I forgot to specialize my question. CRCN patch in ns2.31 to provide cognitive radio capabality in ns2. CRCN patch enable the ns2 to simulate cognitive radio network successfully. I hope anyone who is expert in ns2 can help me. Thank you

I read a paper on cognitive radio, and simulating such a network appears to be graduate-level University material. However, I did find out that there is a PU model table. You would be best off installing eclipse and browsing the source code for the CRCN patch.

Eclipse will allow you to browse the source in oo mode.

Re #2, @frankbell

ns2 : Plenty of CRCN ( Cognitive Radio ..) in the 42 crcn threads → LQ Search
http://www.linuxquestions.org/questions/tags/crcn/

Re #1, @cai : Which CRCN patch ? I don't find any {PUmodel.cc, PUmodel.h}.
Searched in CRCN, CRN, CRAHN, D2CARP.

* ns3 has src/cognitive/model/{pu-model.cc, pu-model}. (Unsupported?)

where can I find the PU model table? Is it in the CRCN folder?
