Hi all,
I want to know how can I set the local time of each mote programmatically ?
I want to set different local time for each node then test my
synchronization algorithm on them.
I used the LocalTime interface to get the local time but i can't set
different initial local time for each node.And
Hi All
I want to know what is the best way to get the residual battery (energy) on
the MICAZ motes ? I need to calculate this intermittently and based on the
value make some decisions so I really need this. I would appreciate if
someone who has worked on similar issues can guide me with this
The telosb doesn't use a real serial port, it's USB.
I'm not clear if a baud rate is relevant, although it
appears that the USB serial comm emulation drivers have
a setting for such.
In any case, I once did measurements with the micaz using
a USB-serial adapter cable and got around 200 normal
Akankshu,
To the best of my knowledge there is no sure-fire way of determining how
much residual energy the batteries contain. I believe the MicaZ has the
ability to take ADC measurements on the battery voltage itself (using
some regulated voltage as a reference). However, this won't
20 to 25 messages per second is just about all the mica2 can handle
so you may just be overrunning the radio.

Hi Paul
Thanks a lot for replying. Actually if I break down my energy consumption, a
majority of it would be in radio communication and the second would be
sampling through the ADC (I am doing high sampling giving the ADC a free run
at approx 17 KHz ). Is there some analysis of energy consumption

In tossim, the node object in python has a bootAtTime method which
lets you set when the mote boots. You can use this to make the local
clock's offsets different from each other. By the way, TOSSIM does not
simulate clock skew. This might limit the validity of the simulation
results.

Hi All
I am trying to implement a clustering algorithm and for that I want to make
sure that the Receive mechanism applies only to the clusterhead.
Regular Nodes:
- samples data
- Transmit packets every few seconds
Clusterhead
- samples the data
- Receives regular node packets
- processes the

}

{

Look at the micaz NESDOC (google nesdoc)for how to turn off the receiver
for the radio.
The real problem you are going to run into is how does the
non-clusterheads know when to become the new
The baseline implementations supporting TimeSyncAMSend do not appear to deal
with Receive.receive correctly, in that the length parameter passed in
includes the timestamp. This breaks code that attempts to validate messages
by comparing that length with the size of the expected structure.

Hi Paul
Please let me know if there might be a way to change the transmission power
level , depending on whether a node is a clusterhead or a regular node. I
just want to reduce interference and save energy ???
Thanks a lot. I look forward to hearing from you.

Hi Janos,
thanks for reply.
What's the meaning of this numbers ? I set the bootAtTime event as these :
*t.getNode(0).bootAtTime(1024);
t.getNode(1).bootAtTime(1320);
t.getNode(2).bootAtTime(6000)*;
And i get the time by *sim_time_string()* method and it print the boot
times as this :
Mojtaba,
Actually, i believe the bootAtTime is in 100's of pico seconds (10^-10)
seconds. So 1024 * 10^-10 = 0.001024, and apparently
sim_time_string() returns time in seconds (up to nano seconds (10^-9)).
There are actually 1024 milli ticks per second, so this is why each
timer fired
Paul,
Thanks again for your clear answers.
Yes, I think like you.So due to this issue I can't test time synchronization
algorithms in TOSSIM,am I right ?Or maybe there is some interface for doing
this job .. ?
sincerley,
Mojtaba

Hi all,
I've just signed up to the tinyos-help mailing list today - I'm a student at

for a MSc in Communications Software and as part of my research I have
undertaken a dissertation looking at the XMesh routing protocol.
Hi,
We are implementing a Transport Protocol on Tinyos-1.x mica 2 environment.
Our transport layer functionality seems to be working between 2 adjacent
motes (single hop).
Now we plan to extend it to multi hop and are looking to use an existing
multi hop routing already existing in tinyos-1.x.

Thanks Phil. I also observed in my deployment that when I move some nodes,
