Hi all,
I found this previous post from Dec. 19th in tynios-help and I would
like to have some points clarified.
First, I agree with Phil that the received signal strength will be
(assuming waves are in phase) the addition of both desired signal's
power and existing noise power level.
As far as

Hi,
I noticed that TOSSIM uses the following formula to compute RSSI:
rcv-strength = (int8_t)(floor(10.0 * log(pow(10.0, power/10.0) +
pow(10.0, noiseStr/10.0)) / log(10.0)));
(in CpmModelC.nc)
I notice that this is adding the signal power (gain) and noise
levels. I am wondering if

Hi,
From previous posts to the mailing list I've noticed that retrieving
RSSI values was never implemented in TOSSIM for TinyOS 1.x, but that
(from Phil Levis's post):
TOSSIM in 1.x doesn't model RF signal strength. (2.x does, but
it does not yet make it accessible to
