Smile Cognitive Radio Network parameters setting


Dear Friends
I just got the CRCN on NS2 installed, the test.tcl and test4wcett.tcl works very well.

However, here is the problem, how to set different control parameters? for example, set the CRN bandwidth vary around (50-150)MHZ step by 10, set the various packet sizes and set the transmission rate. Then the throughput and delay will changed, and can be traced and recorded.

Specifically, I want to see the CR network performance(throughput, jitter delay.etc) under time varying condition or environment.

Maybe the test4wcett.tcl have already provide a time varying environment(i.e various bandwidth, different transmission rate). if so, how to get statistical record for the various bandwidth, because I only saw the different packet size appears in the trace file, after I run the test4wcett.tcl. If not, how to set those control parameters?

Do you have any ideas? or any suggestions?
Thanks in advance!!

May be check the options you can vary with CRCN.jar, the CRCN GUI

thanks!! knudfl

maybe I asked too many question in one time,
can I ask, does the bandwidth in CRCN (test4wcett.tcl) varying, if the bandwidth is changing how can I extract the bandwidth, if the bandwidth is not changing, can i set different bandwidth for the CRN and how?

let me know if you have any ideas

again, thank you very much!!
