[Tinyos-help] Troughput, time synchronized & low power on TMote
We are experiencing problems when trying to transmit data with high bit rate and at the same time have the network synchronized. We are aiming at getting a system working that fills the following requirements: * All network nodes must always be time synchronized. * The network shall be able to transmit highest possible data speed (typical 500 packets/s) * It shall be possible to switch to "low speed and low power mode". This shall be done in runtime. Is it possible to put these requirements into practice? We have studied the NetSync and NetWake code, but are still very confused. We would be very grateful if you can provide us with an example code which meets the requirements above. -Jörgen ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
SV: [Tinyos-help] Questions on NetSync and lowpower
Hi
I need a description of the contents in the file NetSync.h and NetWake.h.
MOTEIV_LOWPOWER_DUTYCYCLE ?
TIME_PERIOD ?
TIME_SYNC ?
TIME_TIMEON ?
TIME_TIMEOFF ?
TIME_EXPIRE ?
TIME_DELAY?
INVALID_HOPCOUNT ?
NETWAKE_MIN_INTERVAL ?
What happends when I compile with LOWPOWER as in "MAKE TMOTE LOWPOWER".
I will dynamically switch the dutycycle of the radio on-time without making a
new compilation. Low power most of the time and high bandwith short times (60
minutes a day).
Best Regards
Jörgen

Ämne: SV: [Tinyos-help] Questions on NetSync and lowpower
Hi Joe,
When I don´t compile with "LOWPOWER" I don´t get GlobalTime.isValid() = TRUE,
why?
How can I get both synchronization and full bandwith on the radio?
How can I switch between LOWPOWER and HIGHPOWER in realtime. I need the full
bandwidth about one hour a day. The reset of the time I will run the Tmote in
low power mode.
Best Regards
Jörgen Johansson

Hi Henric,
The UART is always on, even in low power, if the node is connected to
a base station. The radio is only on when NetSync defines the global
periods.

SV: [Tinyos-help] GlobalTime in Tmote from Moteiv
How synchronized (us) is GlobalTime in different nodes?
Is it possible to get an event e.g. once a second from GlobalTime?

[Tinyos-help] GlobalTime in Tmote from Moteiv
How can I access the GlobalTime from my code? I will have a main node as a time master. Is the timesynchronization only active when compiled with "lowpower"? Shall I include the file GlobalTime.nc or shall I wire the NetSync component? What´s the accuracy of the GlobalTime? My application is a system that will wake up one hour once a day. At that hour I will send as much data as possible. The rest of the time I will save power and only listen for a wakeup command.
