You can check the node id of the source at the receiver in the following way :
1. assign address at compile time : make install.1 mica2 ...... , will assign
address 1 to the node being programmed.
2. The address parameter can be accessed using
TOS_LOCAL_ADDRESS/TOSH_LOCAL_ADDRESS . Assign this value in the
address field of the TOS_Msg which you transmit to the base.
TOS_Msgexample->addr = TOSH_LOCAL_ADDRESS.
3. at the receiver in the receive event check for the node address.
The above steps have been tested with TinyOS 1.x for mica2 and cricket hardware
with XP and work fine.
For accessing the fields within received messages check OscilloscopeRF code for
radio communication. Information on the TOS_Msg structure can be found in
cygwin\opt\tinyos-1.x\tos\types\AM.h file.
Hope this helps,
Aneeket.

Hello all
I want to access source address in main at base station. Can any one
tell me how can I do that. I couldnt get much info about cracking
received packet and accessing Node id of source node. The thing is I
want to receive messages from specific nodes at some instances.
