Check out, from the series of methods, the program follows for transmit
mode, where do they actually turn on the radio, i.e. the startVReg command
and then start your time from there. Well, for CC2420 radio, the default
MAC availabe in Tinyos source tree is B-MAC+, which is a contention based

Dear Han,
True, as I already mentioned that its has been some time that I haven't
looked into this code, and am not sure whether this is the most up-to-date
copy of the code I have actually used, so looking at what I have sent to
you, it just profile the receiving mode of the radio.
So what you n
Hi,
Regarding the last email, I believe the radio in the so called "hearing
mode" consumes as much as "receiving mode" as the radio reception circuitry
is ON. The idle mode is when the radio is turned off. That is exactly what
Low Power Listening (LPL) BoX-MAC does.
I suggest for a detailed energ

Dear Wasif,
Thank you for your help. I've r
no don't go in that direction, just calculate the time radio itself spent
in either of these states, look into my code, in the CSMACA component, you
will see how I am using the Anlyzer component to calculate these times.

Many thanks it's very helpful.
I see what I come up with and i'll let you know

It should not be a problem to port it, well, It has been some time that I
haven't used it so I am not sure whether it is the final copy that
I evaluated, so for you, please go through it, understand it and please do
let me know if you see any anomalies.

You can do online Energy profiling, calculate the on and Off time of the
radio and then multiply it with the current consumed in each of that state,
and actively log it serially. It a bit difficult to monitor all the modes
of MSP430 and CC2420, so I would suggest to monitor CC2420, for its send

No, but I could design in a power measuring sensor,
(that would run on a separate battery or super cap of its own),
I'm currently facing the same problem.
I've already run some tests and it seems quite difficult to correlate the
voltage with the real consumption even having a battery model.

Dear all,
I'm working on deploying a network of 30 telosb sensor nodes. Node works in
a duty cycle (sleep and active modes) and is powered by using one pair of
batteries (3V). Now I want to measure the energy consumption of each node. I
use the VoltageC component to measure the actual voltage of

I just looked at the tmote specs and it shows a bit higher current

use of the radio is the issue, also look up "Low Power Listening" and
see if it is of any use.

Hi Guys,
I have any problem with current consumption on telosb. I made some
tests and the normal energy consumption is 19,5 mA when radio interface
cc2420 is up, while when cc2420 is down the consumption is 0,125 mA.
How can i lower the max Value?
