Hello David,
Thanks for such a detailed reply. I am trying to add the powertrace
or Energest to the border-router code. I added power trace sucessfully and
can get the log of the captured data in the file, but i want to ask that
how we can manuplate the result. For Energest I am trying to figure out
where to insert the code to measure any uptime for router and then get
power results. If you can give clue about this, I will appreciate. Still
thanks a lot regarding the explaination of previous question.
Regard's

Energest uses wraparound macros to count the number of rtimer ticks in each
state - high and low power cpu, radio rx and tx, led on, and whatever else
the platform wants to keep track of (time spent doing CCAs). The power
consumption of a state times the time spent in that state is the overall
energy used by that state; divide by the number of seconds since boot and
you get the average power for that state. The powertrace and compower
routines use energest along with a periodic difference of the rtimer ticks
to get average power over a shorter period of time or for particular
network
modes. The energy calculations are platform and cpu dependent so there is
no
overall routine to print the results.
However the fraction of time spent in each state can be calculated
independent of platform. Webserver-nano shows that on the status page in
static unsigned short
generate_stats(void *arg)

uint16_t numprinted;
uint16_t h,m,s;

Subject: [Contiki-developers] What is Difference Between The Energest
andPowerTrace
Dear all,
Can anyone tell me the difference between the Energest and Powertrace? Do
these 2 serve the same purpose? I have used the powertrace and I can get
the
prints but don't know how to manuplate them to get the power results/grap
from the log file. Is there any tool in the contiki where I can input that
file and see what is the power being consumed?
Also is there any Energest tool to input the print results of the Energest
and get the results with labs in Contiki tools? Which one is more accurate
?

Hello everybody,
Is it normal that in a testbed of 15 motes (TelosB) running RPL, DIS
messages are completely absent in the nodes outputs?
Thank you in advance for your answers.Erij

Nodes should output a couple of DIS at boot, after the mesh forms then only
if the dag is lost, unless you have defined RPL_DIS_SEND to be zero.
$grep -R dis_output *
$grep -R RPL_DIS_SEND
#ifdef RPL_DIS_SEND
next_dis++;
if(rpl_get_any_dag() == NULL && next_dis >= RPL_DIS_INTERVAL) {
next_dis = 0;
dis_output(NULL);
}
#endif

Week & Full Program Now Available
Content-Type: text/plain; charset="us-ascii"
Dear Colleagues,
We're happy to inform you that the program of ACM MobiCom 2013, the 19th
International Conference on Mobile Computing and Networking is now
available at
http://www.sigmobile.org/mobicom/2013/program.html
In addition, we would like to remind you that the deadline for discounted
early registration is in one week, on August 30th, 2013.
ACM MobiCom 2013, the Annual International Conference on Mobile Computing
and Networking, is the nineteenth in a series of annual conferences
sponsored by ACM SIGMOBILE dedicated to addressing the challenges in the
areas of mobile computing and wireless and mobile networking. The MobiCom
conference series serves as a highly selective, premier international forum
addressing networks, systems, algorithms, and applications that support
mobile computers and wireless networks. In addition to the regular
conference program, MobiCom 2013 will include a set of workshops, panels,
research demonstrations, and a poster session that includes the ACM Student
Research Competition. This year, MobiCom is also introducing a new mobile
app competition and a new session of invited industry presentations.The
conference will be held in Miami, Florida, September 30-October 4, 2013.
We hope to see you there.
