okay i got it..i think tossim seems to be the problem. I also read it
somewhr that there is some problem with printing the strength value on pc.
Thanks,

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

Thanks for the response , please can anyone advice if theproducts on the website http://www.smileymicros.com/ isequally good for the practical understanding of TOS. I would like to have a practical feel of the functionalities of TOS and need a constant practise all comments are welcome...
Hi ,Is there any guy out there who is successful in getting the results from this experimental setup:MTS420 sensor with MPR400 (mica2 mote). The mote is programmed with /opt/tinyos-1.x/apps/TinyDBApp.On thePC side , we are viewing the results in TinyDB GUI using the following command
Hi Marcus,
This question seems to come up fairly often so I'll take a stab at giving an answer.
I see from the attached files that you're running TOSSIM under Windows. This is the problem.
My understanding is that if you are running TOSSIM under Windows TinyViz will not work (at
least not for

To the best of my knowledge, the MTS420 has never worked with the
mica2's and TinyDB. The behavior you see (large gaps between epochs,
lots of readings with NULLs) is consistent with TinyDB timing out on
calls to getAttr which never return a value.

How can i consider these time in seconds or milliseconds? i ran a TOSSIM
simulation and i found these times of booting:
SIM: Time for mote 1 initialized to 2477084.
SIM: Time for mote 2 initialized to 2200990.
It's quite urgent, if anyone knows..
Thanks

Recently we r trying to run tinydb with mts 420 sensors , we are
getting null values for pressure,humidity..
We traced the code and found the Pressure.getData() function neither
returns fail nor signals dataReady event.
Can anyone put sum light on this issue.

TOSSIM in 2.0 takes a more extreme position, where the simulator
itself is a Python object (removing the Tython/TinyViz overhead of IPC):
Never saw it before, but looks interesting.
However TOS was designed to be used with the mica Motes
and has been extended to some other products, like Tmote.

Hi ,
I notice that when I put the CC1000Radio (in tos/platform/pc ) in low

side but the receiver does not receive the packet. When I put debug
If you can program the mica2 but not receive data you probably have the

the reset push button, should be in the OFF position. Please don't ask

First, do the format flash part (tinyos-1.x/apps/TestDeluge/FormatFlash/)
compile the code in that folder and program your motes.
next, go to the DelugeBasic folder
(tinyos-1.x/apps/TestDeluge/DelugeBasic/) and compile your code and
program with the id's you want to use.

oops. hit send too fast there.
now, like i was saying, once you've programmed them with DelugeBasic, plug
in one of the motes in the programmer board and then use the Deluge tools
to write the Goldenimage into the goldenimage image :).
then follow the instructions in the manual:
Hi all, I am trying to implement SMAC and got the code from the site. When i give the command make tmote it says " Unknown targetKnown targets for TinyOS directory /opt/moteiv/tinyos-1.x/tosand the specified include directories are: tmote atmega8 mica mica128 mica2 mica2dot micaz msp430 pc rene2
check your tinyos-1.x/apps/ folder to see if the Makerules file lists all
the platforms you have to use. If not, the file should be available on the
Tinyos.net website - http://www.tinyos.net/tinyos-1.x/apps/Makefile
I couldn't find the tmote Make-rules in there though. Someone else might
Yes.
Although, I've programmed them with group ID 7D (default). This shouldn't
matter as TOSBase simply reads the packet sent over the UART and
substitutes the current group ID when transmitting.
Quick doubt - are you framing a message AROUND this packet?
I mean are you sending the packet 7E
Yup,
The code sends out a packet every ~1.5 seconds on the radio. A TOSBase
mote connected to a PC should be able to pick it up.
-shrug-
You're welcome and please do keep me posted. Curious to say the least.
Sankar.

I am not too aware of the Neighbourhood graph. But its a relatively simple matter to code it yourself. Have each mote broadcast a Hello packet. All its neighbours will receive the packet and can record the node IDs in a link list or array. You can even simultaneously record the RSSI and come to
Hi all,
I am simulating a application where i need to find the transmission delay in TOSSIM. So I used time stamps to find the delay for a packet. The delay was varying from 20ms to 40 ms. This was due to the fact of Backoff delay. Since this is a randomly chosen delay, I made that to a constant
