Re: [Tinyos-help] RSSI strength
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.

this is my (a colleague's) code:

doesn't look too different.
although our experiments were done on the actual motes and we broadcast the

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.

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.

Re: [Tinyos-help] TinyOs Help - TOSSIM
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 the more recent versions of TinyOS anyway). This is because the newer versions of TinyOS (from October 2005) use POSIX threads when running in Windows. TinyViz is a Java application and Java uses Windows native threads. The result of this is that TinyViz is unable to load the TinyOS shared objects into the running TinyViz interface which is why you can see the motes in TinyViz but not get them to run. If you run TOSSIM in Linux TinyViz should work (at least all of the versions in the last year or so worked for me anyway). Mike Note: I could be completely wrong about this so if anybody knows better please correct me. I'm basing this on information from the Viptos website: http://ptolemy.eecs.berkeley.edu/viptos/ Quote: Note: As of 10/05, Windows users will not be able to run TinyOS models inside Ptolemy. The reason is that reloading the TinyOS shared objects into the running Ptolemy interface fails because the TinyOS shared objects use pthreads and under Windows, Java is using Windows native threads.

Abishek -- To the best of my knowledge, the MTS420 has never worked with the mica2's and TinyDB.

[Tinyos-help] Application loses packets when using Low Power Listening on TOSSIM
Hi , I notice that when I put the CC1000Radio (in tos/platform/pc ) in low power listening(LPL) mode, the application loses packets although lossy radio model is not used. The event sendDone gets called on the sender side but the receiver does not receive the packet. When I put debug statements to observe radio operations, I found that receiver mote does not get a chance to run until the sendDone is called on the sender mote. I set both the listening mode and transmit mode to the same value as explained in the CC1000Radio Manual ( http://www.tinyos.net/tinyos-1.x/doc/mica2radio/CC1000.html ). The same behavior happens irrespective of the mode except always on mode. When I use the radio on always on mode, no packets are lost and everything works fine. Why does LPL makes packets to be lost?

Thanks for your reply. I was using a general serial-port application to send data to the mote, because I want to have my own application to control motes. My steps:
Firstly, I created a data file with TOS_Msg type; then the application read it and sent data to the base mote through serial port; I programmed the base mote with TOSBase, and tried to check received data in event
UARTReveive.receive. Yes, you are right; the length should be 6. But I'm not sure if the address should be 0x007e, since I'm trying to send data FROM PC TO MOTE through
UART. Anyway, even when I changed the two fields, Msg-data is still not correct. I read SimpleCmdM.nc, which is used when injecting packets (Lesson 7 in Tinyos tutorial). It seems that the received data is also TOS_Msg type
(see task void cmdInterpret). I'm really confused. Thanks a lot. Best, Lei On 6/5/06,

Hi, all I am trying to send a packet from a PC to a micaZ mote through serial cable. The packet looks like:
7e 42 ff ff 0 81 10 f f f f f f a1 21 7e header datacrc (I put two random bytes in the crc field, but I think that's not a
big problem since it doesn't filt out CRC-error packet.) At the mote, I read the received data in event TOS_MsgPrt UARTReveive.receive
(TOS_MsgPrt Msg) {}. The header is correct, but Msg-data[0] is always the last CRC byte, here 0x21, and I didn't see the data section (0xf) in Msg.
Did I make a right packet? How could I send data to base mote throught UART correctly? Thanks!

check your tinyos-1.x/apps/ folder to see if the Makerules file lists all the platforms you have to use.

Fwd: Re: [Tinyos-help] Re: Packet format from PC to base mote through UART
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 ... 7E directly to the serial port? And if you're using MATLAB, could you use the fwrite() function rather than the fprintf()? How about writing a short bit of code to write stuff out to the UART of the mote. Tell you what - attaching the code: MessageSender, save the attachments in a folder in tinyos-1.x/apps/(folder name)/ and program one mote with it, program another with TOSBase and check what the output on the serial port of TOSBase is. This should give you an idea about correct CRC packets etc, and maybe you can find the correct package format to send. 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.

[Tinyos-help] Setting Baud Rate in B-Mac
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 number of 2. When i resimulated that, the delay was constant throughout the execution(10ms between a pair of node) My question is, the transmission delay or the time to transmit is a function of BAUD RATE. As the BAUD RATE is decreased, the time to transmit should also increase. In my application, the PREAMBLE length is 28 bytes, SYNC is 2 bytes, Message size is 15 bytes inclusive of payload and header and CRC is 2 Bytes. If we consider 19200 kbps (38.4kbaud), then Time to transmit = (PREAMBLE + SYNC+Message size + CRC) * 8 / 19200 = ((28+2+15+2)*8/19200)*1024 = 20.0533 ms But the simulation results were showing 10 ms. When the BAUD rate was changed, i.e., to 0.6 Baud, the time to transmit must increase to 300ms. But the result remained 10ms only. The file that i used to set the Baud rate is cc1000const.h and cc1000controlM.nc. Any changes in the BAUD rate were not effecting the simulation results(delay). Is my approach for setting the Baud rate is correct??? Do we have anyother file to set the BAUD rate for TOSSIM??
