Thank you R. Gravina,
Sorry, I didn't understand you response about power consumption. Please can you
clarify more?
What about the RSSI , Average Reception Ratio, and Wireless Transmission Delay
(sec) measurement?
have you any idea ? How can i measure them ?
Thank you very much

Hi,
there is a recent thread on this mailing list about the power consumption of
motes. It seemed to me quite clear, could you check it out?
As for the execution time, you could use the interface LocalTime and wire it to
LocalTimeMilliC *** FOR MILLI SEC PRECISION *** or
Counter32khz32C *** THAT USES THE CRYSTAL OSCILLATOR *** or
Msp430CounterMicroC *** FOR MICRO SEC PRECISION *** However, i wouldn't
suggest using this one as the accuracy it's very weak.
I use the command "call LocalTime.get()" to obtain the current time before and
again after a certain piece of code i want to measure. To read the execution
time, you can send a message over the air or use the printf.
Cheers,
Raf

Hi,
I'd like evaluate the performance of my project based on Telosb and TinyOS
(measure of time, consumption, RSSI, gain (dB) ).
Can one help me? Ho can I do to obtain this values?
Thanks in advance ______________________________
