Dear friends,
The paper entitled "EVALUATING THE USE OF MOTES AND TINYOS
FOR A MOBILE SENSOR PLATFORM"
evaluates 802.15.4 (beaconmode) on a real sensor network of micaz
and telos motes.
Suprisingly, it says beacon mode can not be supported on
capabilities that present motes posses. Any comments on the paper
will be very useful.......
please google for the paper as attachment mails are bouncing back!!!!
I'm not sure if I understand all of the conclusions made in the
paper; among other things, Jonathan Hui and Joe Polastre implemented
802.15.4 beaconing mode as part of the implementation of SP.
For example, in section 5.1 you state that 15.4 requires a periodic
20 symbol timer, and that this makes it impossible to implement
properly. I don't think your statement is correct. It requires a
timer with a fidelity of 1 symbol, but there's nothing there that
means that you need to fire a timer every 20 symbols... why would you
need to do so? You're picking a random number in the range of random
(2^(BE-1)) unit periods...
Phil
