[Tinyos-help] plzzz replyy..... looping stream buffers inside bufferDone or readDone ??
Hi All I am trying to loop the readStream interface for a microphone. For this I am calling the ReadStream.read(period) on a buffer (This is done inside Boot.booted ()).Once the buffer gets filled it signals bufferDone and since I am using just one buffer it immediately signals readDone. Now I want to make this flow continuous... so I tried the following two things : 1. I called Readstream.read(period) inside a task which was posted inside readDone. thus it will be executed some time after readDone gets finished. 2.. I created two buffers of half the size and posted the both in Boot.booted() while bufferDone gets signaled I keep a flag and keep altering the postBuffer calls inside bufferDone to switch between the buffers and then call readStream.read(period) from readStream.bufferDone itself I am not sure if this is correct ? Can someone plzzz help me out here. I want to know if there is a standard way to do such a thing since I assume similar implementations would have been done earlier as well. I look forward to hearing from someone atleast.

[Tinyos-help] CollectionC protocol for mobile WSN?
Hello, Does the CollectionC protocol work for the WSN where the topology of the network changes ? the nodes are mobile but the connectivity is always there.

[Tinyos-help] ReadStream actualPeriod wrong?
Hi All
I have implemented the readstream interface for the microphone but since I
am doing high sampling (10KHz) I decided to check whether I am actually
getting a sampling period close to 100 micro-secs. When I try to printout
the actualPeriod from inside readDone I get the value 370 continuously (I am
looping the calls by posting tasks)
I would be fine with 370 micro-second as the period as well but the problem
is the LED indicators as well as these print statements (instead of coming
at a very fast rate considering my buffer size is only 1000) come at almost
1 per second. Is there a hardware limit that I am reaching ??
I have the following code:
===
event void ReadStream.readDone(error_t result, uint32_t actualPeriod)
{
if (result == SUCCESS streamSuccess)
{ printf(Actuall Period is: %ld\n,actualPeriod);
printfflush();
post sampleData();
}
}
task void sampleData(){
call ReadStream.postBuffer(buf1, BUF_SIZE);
call ReadStream.read(128);
}
===
I would be grateful to anyone who replies !!!

Re: [Tinyos-help] AMSend.sendDone event isn't signaled...
Mojtaba,
Make sure when you are setting up your links in the simulation you set
up BOTH directions of the link. For example if you're trying to send
something from node 1 to node 2, you need to define the gain for link
1-2 and from 2-1. Otherwise, 1 will be able to send to 2, but 2 will
never respond with an ACK.

Re: [Tinyos-help] AMSend.sendDone event isn't signaled...
Mojtaba,
Which node is 1 sending to and when??? I see that the node boot times
are pretty far spaced apart. It could be that if you're sending from 1
to 2, node 2 is not booted up when node 1 sends, thus, it will never
receive an ACK and sendDone will never be called.

Mojtaba,
Make sure when you are setting up your links in the simulation you
set up BOTH directions of the link. For example if you're trying
to send something from node 1 to node 2, you need to define the
gain for link 1-2 and from 2-1. Otherwise, 1 will be able to
send to 2, but 2 will never respond with an ACK.

[Tinyos-help] stm25p volume always valid
I am trying to store a small value in stm25p flash memory
on a telosb mote, using ConfigStorage in TOS2. However,
After mounting, ConfigStorage.valid() always returns TRUE,
even after imaging and mount and before fist commit. Thus,
I am unable to discern the first boot and seed that storage
position. Is this a known bug? I mean, the specification says
that after imaging ConfigStorage.valid() should return FALSE
after mounting but before first commitafter imaging, right?
For example, the following code should cause the led0 to
turn on after imaging, and led1 to turn on after reboot:
event void Mount.mountDone(error_t e)
{
if ConfigStorage.valid() { call Led.led1On(); }
else { all Led.led0On; }
}
For me, led1 always turns on even after imaging.
Thanks,

Re: [Tinyos-help] correlation between ADC sampling and radio communication
Hi Zainul Thanks a lot for replying. Actually I am giving the ADC a free run with prescalar set to 32. So I am expecting a sampling rate of 32 Khz so that even with the added delay of radio communication I should be getting 10Khz (which is my minimum requirement). Also, I need some guidance on clustering... I want switch clusterheads once energy levels goes below a threshold. I think this is same as the LEACH protocol. Can you guide me with this ?

A default sized packet on the MicaZ takes about 1ms (give or take a little) to transmit, when the channel is available. The ADC is internal to the ATMEGA and the radio uses the SPI bus. The number of samples you miss will depend on how your interrupt routines are set up and how rapidly you are sampling the ADC. With low rate rate sampling (100Hz), you will not notice missed samples. Above 100Hz, you will start missing interrupts during radio transmissions. If you get to really high rate sampling (~500Hz), you will probably be limited by the computation you can perform in real-time on the stream of data. Zainul. 2.

[Tinyos-help] Timer accuracy in MicaZ
Hi all, In the application I'm working on, I need to know the exact time of a specific event, so I recorded the time turned on the mote, and I programmed the mote to put the time value in the packet as well (using Time.getLow32() and Time.getHigh32, Time is SimpleTime.Time interface), using this value and adding it to the base time (the time I turned the mote on) I should be able to compute the time which event occured. The problem is that this time increases faster than it should. For example suppose the event is firing a timer in code which occur every 4 seconds, and in the timer event handler, I put the time value and send it to the server PC. In such a test, the difference between time that server receives the packet and the computed time (time value in the packet + base time which I turned the mote on) is zero, but after 15 minutes the reported time is 20 seconds ahead of the current time, and this value increases that for example in 2 days, the reported time by mote is 64 minutes ahead of the current time. The procedure of computing time (recording the mote start time and adding the reported time to it) seems straight forward and correct, so the only problem I can think about is inaccuracy of clock in the mote. I tested this on couple of motes but all of them had the same problem, so do you think if the problem is in the way I implemented my test or it's just some inaccuracy in mote's clock?

Really thanks for your responses.I changed the boot times to 1000,each node

And Node 1 is a sender and every 2000MilliSec sends a packet to
AM_BROADCAST_ADDR (I also changed it to the numbers ,like 2 or 0).But
still does'nt worked.In the first time AMSend.send returns a SUCCESS But the
AMSend.sendDone event is not signaled to change the busy flag for later
sends.I also chanaged the busy flag to false but next time AMSend.send
doesn't return SUCCESS .
Paul, should i active the ACK manually ? Or It's Automatically?
*for i in range(0, 3):
m = t.getNode(i);
m.bootAtTime(1000);*
This is the Timer.fired event :
*ent void Timer.fired()
{

if(!busy)
{
RbsMsg *data = call Packet.getPayload(pkt,sizeof(RbsMsg));
data-count = counter;
dbg(Base,data in the packet is : %hhu.\n,data-count);
flag = call AMSend.send(2,pkt,sizeof(RbsMsg));
if( flag == SUCCESS)
{
dbg(Base,Packet sent %hhu.\n,data-count);
busy = TRUE;
counter++;
}
else
dbg(Base,was not SUCCESSFULL %S.\n,sim_time_string());
}
else
dbg(Control, the busy flag is true.\n,sim_time_string());

And this is my message struct :
*enum {

AM_Rbs = 6
};
typedef nx_struct RbsMsg
{

Which node is 1 sending to and when??? I see that the node boot times are

node 2 is not booted up when node 1 sends, thus, it will never receive an

messages. ACK will arrive at the event will never be signaled. If the
message ACK is active and no ACK is received sendDone is not signaled.

Hi Ricardo,
Thanks for reply. I wrote a dbg statement in first of sendDone event
but ...the sendDone event is not signaled at all!
event void AMSend.sendDone(message_t* bufPtr, error_t error)
{
* dbg(Base,sendDone %s .\n,sim_time_string());*
if (pkt == bufPtr) {
busy = FALSE;
}
}
There isn'nt any statement to print while simulating
Really confused! What's your idea ??
Does it related to Radio configuration of simulation code ?(python
code ?)

Hi,
Im writing a simple application to test send and receive of motes

after
sending so the busy flag does'nt change to false. and in the next time

Re: [Tinyos-help] AMSend.sendDone event isn't signaled...
Mojtaba,
If you are sending messages to AM_BROADCAST_ADDR, then there are no
acks, so sendDone should be fired as soon as the radio successfully
sends the packet. If sendDone isn't firing then this must mean the
radio isn't able to send the packet. The only reason that I can think
of that could cause TOSSIM to fail sending a packet is if CCA always
thinks that there is a packet being transmitted.
I would recommend you closely follow the .py example file given in:
http://docs.tinyos.net/index.php/TOSSIM#Configuring_a_Network
Especially the part that deals with the Noise Model. I seem to remember
having problems with my applications when i tried to skip using the
noise model. This may be what is causing your problems. I'm not very
familiar with TOSSIM, but i believe it uses the noise model to run the
CCA check. If no model is created, then i'm not sure how it determines
what energy level the simulated radio is sensing during CCA, and what
threshold it would use in that case.
Let me know if this solves your problem.

Really thanks for your responses.I changed the boot times to 1000,each

And Node 1 is a sender and every 2000MilliSec sends a packet to
AM_BROADCAST_ADDR (I also changed it to the numbers ,like 2 or
0).But still does'nt worked.In the first time AMSend.send returns a
SUCCESS But the AMSend.sendDone event is not signaled to change the
busy flag for later sends.I also chanaged the busy flag to false but
next time AMSend.send doesn't return SUCCESS .
Paul, should i active the ACK manually ? Or It's Automatically?

Mojtaba,
Which node is 1 sending to and when??? I see that the node boot
times are pretty far spaced apart. It could be that if you're
sending from 1 to 2, node 2 is not booted up when node 1 sends,
thus, it will never receive an ACK and sendDone will never be called.

Mojtaba,
Make sure when you are setting up your links in the
simulation you set up BOTH directions of the link. For
example if you're trying to send something from node 1 to
node 2, you need to define the gain for link 1-2 and from
2-1. Otherwise, 1 will be able to send to 2, but 2 will
never respond with an ACK.

Paul,
Thank you veryyy much!!!.It worked!
I had seen this page several times but i wasn't accurate enough and so i
didn't used the noise model at all.
Really you gave me a big help! Thank you.
But what is this numbers ? It claimed that you should use at least 100 entry
of this numbers so the CPM can create the statistical model.Have you any
sources to read more about this topic and it's usage ?
