Re: [Tinyos-help] CTP neighbor eviction procedure
Yes, I think it would be troublesome if one neighbor completely vanishes from the vicinity of a node because in that case node will always be transmitting 3 byte additional overhead in terms of the reverse link neighbour quality.

Re: [Tinyos-help] Reg:MDA 100CB in Micaz mote (SHIVASANKAR GANESAN)
hi, you are trying to connect through a wrong COM port that i suppose as finding COM3 as higher port is near to impossible in windows, in normal cases you will get some port between 9 to 15.Check your port number in MyComputer-manage-PORT and use the higher port allotted to MIB520 in MoteView. have a detailed tutorial to workout step by step.If you need give me a your mail id.And one more thing are you sure you are using Micaz as crossbow supplies normally IRIS motes with MIB520.

Re: [Tinyos-help] message received
Hi,
I'm not sure what exactly you want to do here. In the receive method you
get a pointer to an object with data you just received. The value you
received is e.g., message-value1. With the line message-value1 -
D1; you are overwriting this value (you never read it). Finally, you
return the pointer to the object with the data, and it will be
overwritten in the future when the system receives more messages. This
will compile, but has no visible effect.
If you want to store the data you received into the variable D1, you'll
have to write D1 = message-value1;. This will change the value of D1
to the value that you received in the broadcast message.
Cheers,
Urs

[Tinyos-help] Forwarding Msg
Hi all, Currently i am working on a project : is about tracking the target inside the mesh network.I will have three types of node .. 1) *Target *: Only board casting the message which contain Hop count , node i d, and temperature 2,)*Relay * : Received the bcast and check the Node it ..if the Id is from the target increase the hop count if the ID is from other relay increase the hop count inside the msg by 1 and re boardcast the msg. 3)*Ancho*r : Received the bcast and check the node ID just like the realy .. but this time the anchor will send the msg directly to the base satation which is within the transmisssion range by fixing the address in the msg. * Implementation... * Assume we have four anchors( position is alrady known) arrange into square form.the distance between the any two anchor is two transmisssion range distance , Some realy node in between . Forming a mesh network and track the target by looking at the hop count from each Anchor. Now my problem is that if i put the base station close to one of the Anchor (A1) .then i am not able to receive the infromation from the rest of the anchor A2,A3,A4. SO now i wan to forward the information from Each anchor back to the base without changing any information. IS that possibile? Currently my program code is working fine for every anchor just that i don't know how to forward the message back to station . HOpe you can understand what i mean..I really need ur value advices. Pls help me and looking forward to ur reply. Thanks for ur time.

Re: [Tinyos-help] CTP: CtpForwardingEngineP component error
Hello!
The return value is EBUSY. The AM layer do not promise signal
AMSend.sendDone
event, if the return value is not SUCCESS when call AMSend.send().
Because in the component AMQueueImplP, when call Send.send() it may
return
EBUSY in two place, as show below:
generic module AMQueueImplP(int numClients) @safe() {
provides interface Send[uint8_t client];
uses{
interface AMSend[am_id_t id];
interface AMPacket;
interface Packet;
}
}implementation {
..
command error_t Send.send[uint8_t clientId](message_t* msg, uint8_t
len) {
if (clientId = numClients) {
return FAIL;
}
if (queue[clientId].msg != NULL) {
return EBUSY; //
.(1)
}
dbg(AMQueue, AMQueue: request to send from %hhu (%p): passed
checks\n, clientId, msg);
queue[clientId].msg = msg;
call Packet.setPayloadLength(msg, len);
if (current = numClients) { // queue empty
error_t err;
am_id_t amId = call AMPacket.type(msg);
am_addr_t dest = call AMPacket.destination(msg);
dbg(AMQueue, %s: request to send from %hhu (%p): queue
empty\n, __FUNCTION__, clientId, msg);
current = clientId;
err = call AMSend.send[amId](dest, msg,
len);//.(2)
if (err != SUCCESS) {
dbg(AMQueue, %s: underlying send failed.\n,
__FUNCTION__);
current = numClients;
queue[clientId].msg = NULL;
}
return err;
}
else {
dbg(AMQueue, AMQueue: request to send from %hhu (%p):
queue not empty\n, clientId, msg);
}
return SUCCESS;
}
..
}
If the EBUSY is returned from (1), it is OK, and the Send.sendDone
event will be
signaled for the client who call it later; but if the EBUSY is returned from
(2), the
problem arise, it do not signal the Send.sendDone event for the client who
call it, but
it will only signal the Send.sendDone event for another client whose AM ID
is different
from the current client later.
I find this phenomenon arises when the EBUSY value return from (2). So
it may be
the component AMQueueImplP have some problem, it can not guarantee the same
semantic for the EBUSY.
Best regards!

I think it is not cased by the channel capacity, but because in
Send.send()
the
clientPtrs[client] be set NULL;
command error_t Send.send[uint8_t client](message_t* msg, uint8_t len) {

}
clientPtrs[client] = NULL;
return SUCCESS;

..
}
if it do not deal with the EBUSY and FAIL state in the else condition, it
will remain NULL. So the
next when call Send.send() it return EBUSY, because the
clientPtrs[client]
only be reseted
in the void packetComplete() function which be called in the event
void
SubSend.sendDone()
as below:
command error_t Send.send[uint8_t client](message_t* msg, uint8_t len) {
..
if (clientPtrs[client] == NULL) {
dbg(Forwarder, %s: send failed as client is busy.\n,
__FUNCTION__);
return EBUSY;
}
..
}
void packetComplete(fe_queue_entry_t* qe, message_t* msg, bool success) {
if (qe-client CLIENT_COUNT) {
clientPtrs[qe-client] = qe;
}
}
because the command SubSend.send() return not SUCCESS, so the event
SubSend.sendDone() will not signal, so the clientPtrs[client] remain
NULL.
The return value is either FAIL or EBUSY in that else block.
If it is FAIL, we should wait until the condition that resulted in
FAIL is repaired. If it is EBUSY, that means we should wait
until sendDone.
I think we are handing the EBUSY case properly.
There is a possibility that we are not handing all the possible cases
that can result in FAIL.
I understand posting sendTask solved your problem but I want to
understand why it works and if there is any FAIL condition that we do
not handle properly before committing the fix. Do you know what return
value you were
[Tinyos-help] Broken Java SDK in Cygwin RPM
Hi all,
I'm new in TOS world and just installed a TOS environment on my Cygwin
environment. I could compile some basic application such as Blink but fail
to compile applications involving the tinyos.jar Java archive (e.g.
apps/MViz).
I installed from RPMs as described at
http://docs.tinyos.net/index.php/Installing_TinyOS_2.1.1#Manual_installation_on_your_host_OS_with_RPMs
The installed RPM for TOS is the one given in the step-by-step install
guide:
http://tinyos.stanford.edu/tinyos-rpms/tinyos-tools-1.4.0-3.cygwin.i386.rpm
When running *make telosb* in apps/MViz the make process terminates with a
bunch of errors:
v...@a05pc01-vb /opt/tinyos-2.x/apps/MViz

...
My CLASSPATH is set correctly but the problem comes from the tinyos.jar
archive which effectively does not contain the message package...
A dump of the JAR content with $ jar tvf tinyos.jar shows that the
bet.tinyos.message package is missing (and perhaps others).
I then tried to rebuild myself the JAR with *make tinyos.jar*
in /opt/tinyos-2.x/support/sdk/java but this also fails (build log in
attached jar_build.txt).
I think that the available Cygwin RPM is somehow corrupt. What is the best
way to go on for me now without having to re-install everything? May I
simply replace my tinyos.jar with one downloaded from CVS ?
Thanks for your help!

Hi again. First at all, thanks for your answer. And first at all again, I haven't give enough data. Sorry for this. I'm a Spanish student working in a thesis about sensors networks. The hardware is a mote based on a ZigBit900 module from Atmel. You can find more technical specifications at: http://cv.uoc.edu/app/mediawiki14/wiki/P%C3%A0gina_principal http://cv.uoc.edu/app/mediawiki14/wiki/Inici http://cv.uoc.edu/app/mediawiki14/wiki/Hardware_COU_1_1 Trying to test Mote-PC communication and following the tutorial indications for TestSerial, I cannot see any leds blinking (like Mario initially). Then, when comment all lines of the event Receive.receive to ensure that only the red led gets on, still no blinking. So I concluded that this event doesn't execute. Communication mote -- PC is ok. I can see the received packets on a terminal. I cannot figure what's happen for the other way PC -- mote, and why this event doesn't work normally. Are the mote discarding packets because a CRC error, for example? It's a baudrate (57600) problem? May be a problem about USB port? I have seen that some people had this problem, but no solutions were revealed. I will appreciate any help. Regards, Joaquín Urs Hunkeler-2 wrote: Hi, Why do you think you have the same problem? It is very important to clearly identify the problem before you can solve it. The problem described below was that Mario wrote his own interface program on the PC and he was not sure about the exact data format on the serial port. What are you trying to do? Which code are you using? What hardware are you using? Do you get any error messages? (If you are using the MIB510 programming board with mica or iris motes, make sure the switch on the programming board is in the off position) Cheers, Urs On 10/30/10 1:26 PM, Joarod wrote: Hi, I have the same problem.

This could have two reasons: (1) you have a wiring problem (as you suggested), or (2) or the type of the message (the value in the square brackets [] before the function parameters) is not the expected value. Personally, since this is not a value that you specify yourself in the code, I'd go with option (2). In SerialActiveMessageC the SerialDispatcherC.Receive is wired for TOS_SERIAL_ACTIVE_MESSAGE_ID, which is defined in Serial.h as 0. Without spending more time analyzing the code I think this means the following. The framing protocol used by the serial connection supports multiplexing different types of messages (why ever they would need this). The ID of the messages used for TinyOS communication is 0, your PC-based code could be sending a frame type different from 0. Ok, I looked a bit more into it: Byte 2 (Framer-level dispatch) is set to 0x45 = 69 = SERIAL_PROTO_PACKET_ACK, which is the only frame type that is handled (see SerialP.nc). Byte 3 (as expected in SerialP.nc) seems to be a sequence number (so make sure to increment it :-) ). (here you seem to miss a byte in your list) Byte 4 is the frame data type If my reading of the source code is correct, this value would need to be 0 (TOS_SERIAL_ACTIVE_MESSAGE_ID). Byte 5-6: destination address (see Serial.h, serial_header) Byte 7-8: source address (see Serial.h, serial_header) Byte 9: length (see Serial.h, serial_header) Byte 10 would be the group ID (see serial_header in Serial.h). The group ID is used to logically separate different sensor networks sharing the same radio channel. Byte 11: AM type (see Serial.h, serial_header) Let me know whether inserting the missing Byte 4 (frame data type) with a value of 0 solves your problems (you might need to update the checksum).

I think the accuracy at 57600 is not high enough. Using the baud rate 38400 the error (jitter) is less and it works. The modules uses a RC oscillator instead of a crystal this circumstances affects less clock accuracy. Now the received data and the signaled event ends in the

[Tinyos-help] how to distinguish between packets received at base station
Hi, I am working on RSSI based location tracking problem with micaz motes. The scenario is as follows: The moving node (whose location is to be tracked) broadcasts beacon signal with seqnum, and nodeid . There are four stationary nodes who receives this beacon packets and extracts RSSI value from the packet. They send the packet with RSSI value to base station which is connected to a laptop to compute location of moving node. The problem I am facing is, the base station also receives the beacon packet sent by moving node and tries to extract rssi from that packet. But this packet do not have rssi value. How can I distinguish between packets received from stationary node and packet from moving node.. Thanking you, Manish. ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
