[ns] How to simulate random intermittent link

[Bo Fu]

Hi,

I want to use ns-2 to simulate some special wireless scenario. But the
scenario requires random link-up and link-down. For example, two node
are still in the transmission range. But the one node randomly failed
(the random can be some distribution, such as gaussian). And this
link-down lasts for several ms before it comes up again. Can I
implement this by ns-2?

Any comments will be greatly appreciated.
