hi there..

i'm really2 need help..
my final project need to evaluate and compare of channel selection strategies in cognitive radio adhoc network..the objective of my project are to compare which strategies will give the better network performance via throughput..I already get the srategies such as common control channel and frequency hopping..but my problem is i don't know how to implement this strategies using ns2..please anyone help me....pleaseeee...really2 need help..

Welcome to LQ.

That's a pig of a project. The best channels are the ones that are not interfered with, or trafficked on by all your neighbours. Channel hopping is a military anti-jamming technique. A lot of radio jamming was done in WW2 and this technique was invented (by a woman) to get around the issue.

Posting the same question twice won't get you any faster/different answers, nor will begging. And spell out your words, please.

There are MANY different NS2 elements you can find with a Google search for radio simulation. Start there...for example, just ONE hit:

...has MANY suggested solutions. If you have a specific problem, please post it.
