[Tinyos-help] Fwd: Simulators for clock drift
Hello, We are studying clock synchronization in WSN. Is it possible to simulate clock drift in TOSSIM? Are there such studies? If not, do you now any other simulator that we can simulate clock drifts for WSN? Regards -- Doç. Dr./Assoc.

[Tinyos-help] Power profiling for MicaZ nodes
Hello, We have MicaZ motes. We want to measure power consumption of our clock synchronization code by software. We want to do this by measuring the duration a componrnt is switched on. Is doing this in our code sufficient, or should we do this in the whole TİnyOS source code. If this is the case is there aynyone who did this already? Regards -- Doç. Dr./Assoc.

Re: [Tinyos-help] Power profiling for MicaZ nodes
Thanks for your help. I examined Avrora. As far as I have seen, it is useful before porting the app. to the actual nodes. However, we want to measure the energy on actual nodes by software. We are working on clock synchronization and my assistan says that it is not possible to test our program with simulators because clocks in a simulator tool are perfect. We will either do this on our program or on source code of Tiny OS by getting the time when a unit is switched on and off. Is the 1st approach (on our oen program) sufficient in your opinion? Regards 06 Aralık 2010 08:52 tarihinde Urs Hunkeler urs.hunke...@epfl.ch yazdı: Hi, The Avrora project does cycle-accurate simulations of programs running on MicaZ and should give you a good estimation of the power consumption of your programs. http://compilers.cs.ucla.edu/avrora/ If you want to do your own measurements, I think both Avrora and PowerTOSSIM did measurements, and how they did it would certainly be described somewhere. The common approach would be to toggle an IO pin of the mote whenever a component is activated/deactivated, and then to measure the timings with an oscilloscope.
