Hi Guys,
I have never used deluge on IRIS before. Is this a recent problem or
has been always the proble? The default low power listening settings
has been reworked recently, mazbe it has something to do with that? Do
you see any other performance problem on the IRIS?
I just tried the burn-net script from apps/test/deluge/Blink and indeed it
doesn't seem to work right on IRIS. I tried to use the CC2420DK sniffer to
see what packets are send over the air and the packets were invalid. :|
I also tried to go back to the version before default-lpl [1] and what I
noticed then is that the tos-deluge fails to properly talk to the mote.
I'm not sure why. As I said above, this works fine in the latest CVS.

Hi Qiu, Razvan,
I have some measurements on how slow Deluge actually is on the IRIS, by
instrumenting the file /opt/tinyos-2.x/support/sdk/java/PrintfClient.java
and capturing debug statements from DelugePageTransferP.nc
To transfer 3696 bytes of data, a whopping 34.42 minutes were spent.
Wow, that's very slow. I was not aware of this abysmal performance on
IRIS. Perhaps somebody familiar with the RF230 can take a look. :D

Do you have any advice on how I can speed up the process? According to my
*preliminary* investigation, LPL is not enabled by default.
Thank you in advance.
Best regards,
Yee Wei

Thanks for your reply. By the way, I found another problem. I see the
CVS code after 09/16 the LPL is default on, but it seems Deluge
doesn't comptiable with LPL, I've found the GoldenImage with LPL
receive data very very slowly, for example, when send a 30K image, I
waited for 2 hours more, but it was still not finished.
Without any configuration the default lpl committed on 09/16 is equivalent
with the always on configuration. If it doesn't then it's a bug that we have
to fix.
Deluge T2 with LPL always took a long time. A deeper investigation might
reveal a way to make it faster though. :-)

Hi,
I know Deluge can reprogram all the motes in a network. But I just want
to reprogram a mote with specific ID. Is there an existing component can do
this? Or is it possible to modify Deluge to achieve this?
In Deluge T2 there is no per-node filtering. The DelugeP.nc from
tos/lib/net/Deluge is responsible for what happens when a node finds about a
new image. The two functions in which reprogramming using tosboot is trigger
are ObjectTransfer.receiveDone and DelugeMetadata.readDone. You could add
some condition to those action if you want.
