[Tinyos-help] question on setNoise(node, mean, variance)

[Liu Haibin]

Hi,

I have a question about the setNoise(node, mean, variance) in TOSSIM 2.x. I
found that the larger the mean is, the more noisy it is. For example,
setNoise(1, -100, 5.0) can make nodes receive packets, but setNoise(1, -10,
5.0) cannot. I was expecting to see that -100 would mean more noisy that
-10. Did I get the concept wrong? So what does the noise here mean? Many
Thanks.


Regards,
Haibin
