Please stop sending me anything about tinyos, because i've compleated my study.
TQ very much for your help n coorporation.

Hi Malissa,
Depending on the platform you are using, your CPU may accept float or even
double numbers. Also, depending on the architecture float computations might
be accelerated with dedicated hardware or not.
So the main points you have to verify is whether the extensively use of
float operations will decrease the overall performance of your system. Of
course, it is not the same to compute a numerical integration than to
average two numbers...
Another main point is the memory footprint. Float numbers typically could
use 4 bytes. So you must take care of how much available RAM you have for
your application.
A final concern is that you can not use network data types (i.e. nx_struct)
for communications since there is not defined a nx_float type.
The other option, instead of using floats, could be to convert to integer,
scaling as many decimals you want. For instance, 165.32 could be converted
to 16532 (remembering that it is multiplied by 1e2).
I hope it helps!
Sergio

Hi,
I've installed the tinyos-2.1.1 from http://tinyos.stanford.edu/ to ubuntu
Lucid Lynx and i want to use Deluge for reprogramming micaz motes. I'm
following Deluge T2 Tutorial (
http://docs.tinyos.net/tinywiki/index.php/Deluge_T2) but occurs errors when
i execute some scripts. Someone has successfully follow this tutorial ?

Good evening everyone,
I work at tinyos 1.X and I use tossim simulator.
my project is about how we can modified the routing table to aodv protocol.
we want know how i can change the operation at this protocol and how i can
