Hi all,
Can someone tell me how does tinyos deals with addressing each node.
If I'm not mistaken you give a TOS_ID when programming the mote, but
is this usable for many motes?
Is there a dynamic addressing? In compile or runtime?
Can someone also tell me how tinyos deals with nodes entering or
)?
Thanks. Regards,

I have a question related to the maximum transmission speed for the

Hi,
You can use the sense example in the apps of the tinyos.
Compile wih
SENSORBOARD=mda100 make iris
or whatever.
You can specify the CB in the makefile by adding

to the CFLAGS.

Hi,
I also made some tests a few months ago with an IRIS mote, stressing
the packet size and periodicity of tranmission. The conclusion is
quite obvious: larger packets = higher data loss (with the same
transmission period).
I tested several combinations of packet sizes and time periods but

TOS2 controls turns the mote into sleep mode when it isn't doing
