Hi,
How is it possible to increase the task queue on TinyOS1.x (micaz motes)?
which files and where do i have to modify?
thanks for your availability
cheers

all,
I wonder if the microsecond-level timer can be supported in tos?

我现在使用Sogou.com的2G邮箱了，你也来试试吧!
Daniele:
you'd try including the CFLAGS += -DTOSH_MAX_TASKS_LOG2=8 line in the App Makefile,
to increase the size of the task queue to 256.

Claro.

Thanks Darren,The real thing I want to do is to limit the radio range to some nodes.I am simulating around 50 nodes and want to form a tree using them. The problem here is that the root (mote 0) broadcast and allocates the even furthest node (consider nodes are placed in a grid fashion)as its

What is the problem?

Hi Ale,
On telosb there is the CC2420Control interface which you can use to
switch on acknowledgments; this is not synonymous to reliable
communication, but it gives you a primitive to implement such. I am told
it depends on the version of your hardware whether it is on by default.
I do not
Hey Nilay,
In TinyViz goto the 'Plugins' menu and enable the 'Radio model' plugin.
Select the corresponding control panel (on the right) and choose the
radio range e.g. 'Fixed radius (10.0)'. You can then scale this by
setting the 'Distance scaling factor'; I believe you must use the
Hi Michael,
The problem is that we need more memory for our project. Even if FLASH memory
is slow, i think we need to use all possibilties that micaz mote gives to us.
Is it possible to use it for writing data? (i know that for ADC readings it is
used, and just to remember we use tinyos 1.x and
I changed the makefile with that line, but results remain the same. I notice in
the simulator some lost packets ,when nodes are transmitting close to each
other. i tried to avoid this by using random timers before sending, but
sometimes there are still lost packets. Now i think the reason is

I wasn't able to fix it. The problem still exists.
What I did instead was, I copied the platform specs from a colleague's pc
and saved it in the tinyos-1.x/tos/ folder.
I also copied his entire Cricket folder and saved it in mine (all of this
with tinyos-1.1.0 in case you were wondering).

can't tell you what the throughput would be for a multihop network because it
would depend on a number of factors, but for a singlehop network of mica2's with
no loss you can expect 1926 bytes/sec using the original CC1000 radio
stack. If node 2 in your network is

The backoff on the mica2 doesn't seem to be as reliable as one would like.
I have a little bit about it in the ACK/reliability report I just ref'd.
You may also have hidden node problems, where packets collide because
two transmitters cannot hear each other.

Perhaps if you use the QueuedReceive mechanism, you'll not loose as many packets? Or, if you really want to be sure you're getting the packets and you don't want to touch the radio stack, try using the RadioCoordinator interface, which allows you to be notified every time a byte is recieved.

Places for TinyOS information...
The downloads:
http://www.tinyos.net/download.html
I advise using TOS v1.1.7 or 1.1.10 with mica2. There seem
to be some hassles with v1.1.11 and higher on some systems
so I haven't upgraded...
The doc/tutorial is a good place to start learning.

I just noted that there is an updated version of this book in your

After I downloaded it, I found there are some samll errors in the code
example we discussed.

I believe that is the case. With the proviso that they

Thanksfor your kind reply Phil and Michael...
What about if i make the nodes to communicate in a single range, and force them to come on hop., which means there shouldn't be hidden node problems..
I did the following to achive the above, for the 3 node network..

Well David, thanks for that.
But i wonder about what you say 1926 bytes/sec, which means its almost 15kbps. I find loss for 5 kbps. it gives almost 5 % loss for node 2 and 0% loss for node 1. Also, i would like to do this multihop testing on a single range, so that i can capture what is
