Re: [Tinyos-help] Reg. Tinynet framework
What is the TinyNet framework? Where did you get it? What version of TinyOS are you using? What platform are you building this for? These are all important questions that should be specified when asking for help. Think to yourself, "How can I make this easier for the people trying to help me?" Want to try again?

[Tinyos-help] Problem with radio packet that is not being updated
Hi all,
I am trying to make a simple localization setup. I have 6 TelosB motes and they
are programmed as follow:
*TelosB #1* - I have installed BaseStation app on it and gave it TOS_NODE_ID
of 1 when I uploaded the program
*TelosB #2* - Is my remote node, I mean I move it close to the stationary
nodes to receive packet from them (the most important part is the recive event
that you can see below:)
*TelosB #3 ~ #6* - Are my stationary nodes. I have set the transmission power
to minimum for these 4 nodes and I have put them in distances like 2 meters of
eachother.
So, I programmed the stationary nodes to send a simple packet to destionation
address of 2, that is the remote mote. And I can see when I move the remote
mote close to stationary nodes, its led0 blinks, indicationg that it is
receiving something from a nearby stationary node.
The remote node then supposed to read the comming packet, and send the
TOS_NODE_ID of the stationary node to BaseStation, and BaseStation simply
prints the packet content on terminal.
Everything works fine, exepct a big problem! After turning on the remote node,
The remote node only sends the TOS_NODE_ID of the first stationary node that it
was near it when it got powered on. When I move to the next stationary node, it
receives packet from new node but it still sends the TOS_NODE_ID of the first
node that ot was near it.
*Example: *
I turn on the remote node near stationary node #3, then I can see on terminal
that the node number was 3...Everything fine so far...Then I move to node #4,
somewhere in the middle of the way to next node, well I dont receive packet
because the transmission power is low. When I reach the node #4, the leds on
remote node (#2) starts blinking and I start to see output on terminal again
but it still shows the node id was 3, so it does not get updated.
If I turn off and turn on again near node #4, then I can see on terminal the
correct node ID, but when I go to another node, it still shows the last node id.
I am sure that I gave correct node ids when uploading the program. So I beleive
this could be a code problem.
Can you please check my code?
*Here is the message in header file that is same for remote and stationary
nodes:*
typedef nx_struct LocalNodeMsg
{
nx_uint16_t NodeId;
} LocalNodeMsg_t;
*Here is the code that sends packets from stationary nodes to remote node:*
//Global vars
bool _radioBusy = FALSE; //indicates if radio chip is busy sending/receiving
message_t _packet; // static storage for making packets
event void Boot.booted()
{
call RadioControl.start();
}
event void SendTimer.fired()
{
if(_radioBusy == FALSE)
{
LocalNodeMsg_t* pkt = call Packet.getPayload(& _packet,
sizeof(LocalNodeMsg_t));
pkt -> NodeId = TOS_NODE_ID; //Assign the node ID to packet
if(call AMSend.send(2, & _packet, sizeof(LocalNodeMsg_t)) == SUCCESS)
{
call Leds.led2On();
_radioBusy = TRUE;
}
}
}
*Here is the code in the remote node that sends node id to BaseStation:*
event message_t * RadioReceive.receive(message_t *msg, void *payload, uint8_t
len)
{
if(len == sizeof(LocalNodeMsg_t))
{
LocalNodeMsg_t *locPkt = (LocalNodeMsg_t*) payload;
LocalNodeMsg_t *pkt =
call RadioPacket.getPayload(&posPkt, sizeof(LocalNodeMsg_t));
pkt->NodeId = locPkt->NodeId;
if(call RadioSend.send(1, &posPkt, sizeof(LocalNodeMsg_t)) == SUCCESS)
{
radioBusy = TRUE;
}
call Leds.led1On();
return msg;
}
REGARDS,
Sean.

[Tinyos-help] Synchronization in TinyOS
Hi all, This question is more a request for advice and/or opinion. Some research articles which deal with synchronization (i.e., aimed at designing some kind of TDMA scheme) in wireless sensor networks, state that nodes can maintain synchronization by exchanging clock skew/drift information with neighboring nodes in coverage area. In other words, maintain any sort of local synchronization. In this sense, in the specialized literature and/or datasheets, it can be found information about the clock skew associated to many devices. For example, in [1], authors indicate that, on average, TelosB introduce 30 us per second of drift; also MicaZ have 40 us per second on average of clock drift [2]. Taking into account the aforementioned, had no global synchronization (a unique node, e.g., the coordinator of the network, conducts a periodic synchronization proccess with all nodes of the network), would be any simple way to make this local synchronization in TinyOS? I mean, is it wise to consider in your synchronization protocol either these values found in the literature (e.g., 30 us in case you worked with TelosB); or exchange timestamps between two nodes and calculate the difference of time; etc.?
