How to use noise under ns2 simulations?

Hi,

I'm working on my master thesis using ns2 simulator. I've done some
simulations under specific scenarios with the "default" values, but now I
need to repeat that simulations "injecting" noise. I've been looking for
that option, but I couldn't find it...

I need to know HOW to implement some noise in my simulations and what kind
of noises are avaliable with the simulator, if there are a "plugin" to
emulate other types of noise, and so on...


Thanks in advance and sorry for my english!
