} }The receiving variable keeps track of whether the node thinks it isreceiving a packet or whether it is searching for packet preambles.You can only start receiving a packet if you are in the latter state
(unless you can recover preambles during packets, which no existingradio stack besides Kamin's prototype mica2 stack can do).The second case is for when the packet is strong enough to hear. Ifthe signal strength is not above noise, then you do not detect the
preamble.Actually, this looks like a very optimistic approach. The logicshould be more like:if (signal is below noise + threshold) { lose packet}else if (already receiving) { lose packet
}else { receive packet;}Note that the current approach resamples the noise but does notconsider the signal threshold. In the end, the difference between thetwo is pretty small (the number of preambles you detect of packets
that might be lost), but still, I should look at it carefully.PhilIn a real situation, the mote can capture a stronger transmission while
it's detecting the preamble of a weaker transmission (when it passes
the preamble and starts to receive the weaker transmission, it cannot
capture the stronger one. But Kamin's prototype can).
But I went through the Tossim 2.x UscGainInterferenceModelC.nc.
I found that even during the detection of a preamble of a weaker
transmission, a stronger transmission cannot be accepted. Because the
weaker transmission will set the receiving = 1 even during its
detection of preamble. However, the stronger will still corrupt the
weaker transmission so in the end, neither of the two transmissions
passes through.
Am I right on it? Or did I miss something?

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?

It simulates atm128 timers at the hardware level, and simulates the radio at a packetlevel. It does not simulate the ADC. The goal is to be able tosimulate each chip, and then when you compile for a platform youcompile the simulation version of each of its chips.

41 CM_lastBit ^= 1;42 }43 }44 }45 }46 return;47 }The
test of 12 consecutive 0's (line 11) is in the state of IDLE_STATE
(line 5), but when it's really starting to receive data, it should be
in the state of START_SYMBOL_SEARCH (line 24). So even when someone is sending a lot of 0's, the receiving node is in the state of
START_SYMBOL_SEARCH, so the test of 12 consecutive 0's (line 11) will never be executed.Cheers,

Re: [Tinyos-help] Re: question on simple_transmit from Rfm_model.c
But according to tossim document, the simple radio model places all nodes in a single cell and every bit transmitted is received without error. So it should not have any hidden station problem.The thing is every time node is transmitting 0s, it is considered not transmitting. That's the part that I don't understand. I'm afraid that it has nothing to do with hidden station problem.

Any wireless xommunication has two problems associated with it

You may want to google these terms to see what they mean. Essentially it means that it is not always possible to detect whether a channel is really idle or not. Thats why CSMA (used by tinyos)will not always work correctly. Newer versions of tinyos implemet the B-MAC and S-MAC protocol which supposedly solves these problems. If youre using older versionsof tinyos (
2.0), you will have to figure out how to tackle these problems on your own at the application level. In my project, i used redundancy i.e every packet was sent 3 times at 500 ms intervals with the hope that at least one of these packet reaches the destination correctly. It worked for me.

[Tinyos-help] Re: question on simple_transmit from Rfm_model.cDate:Mon, 5 Jun 2006 18:04:10 +0800
For example, let's say we have 2 motes. Mote 0 is transmitting 0s all the time, so transmitting[5] = 0, radio_active[0] = 0, and radio_active[1] = 0.
While mote 0 is transmitting 0s, the TOSH_rfm_rx_bit() in TOS_SIGNAL_HANDLER(SIG_OUTPUT_COMPARE2B, ()) of mote 1 is called. And because radio_active[1] == 0, TOSH_rfm_rx_bit() returns 0. After 12 bits, it signal
ChannelMon.idleDetect() to show the channel is free. But actually mote 0 is using the channel and transmitting 0s.Why is it so? Any help is appreciated.
