Sorry I'm a T1/mica2 kinda guy so I'm not much more help.
I assume that the Telos do not transmit directly to a host
but have some intermediary, or base-station. That would be
on place to store samples. I don't know if they have EEPROM
like the mica's though. In T1 there are modules that access
external EEPROM on the micas, SenseLightToLog is an example.
You might also search back over this list for postings on
the EEPROM/Log subject by David Moss. He's done a lot of
work on that subsystem.

Hi,
Thanks for the prompt reply, but I'm using TinyOS-2.0 and TelosB
platforms. How do I locate TOSBase? I saw the TinyOS-2.0 tutorial 7
about Permanent Data Storage, but it concentrates mainly on storing
configuration data, nothing much on writing blocks of data - my question
is, is the implementation similar? I'll search the archives again to
get more info on this, but I'm not too sure if there'll be any that uses
TinyOS-2.0 (most of what I saw so far uses TinyOS-1.x).

Everything is (im)possible with software.
You probably want to modify TOSBase to store received messages
in local EEPROM instead of using a queue to re-transmit to the
UART (search this list for the myriad headaches involved in
getting Log and EEPROM to work). Then you need to add a message
from the host to the base-station which causes it to dump all the
stored messages to the UART when it is reconnected.
No problem at all...

Hi,
I'm not so sure if this question has been raised before, but
assuming I have a multihop network (say, 10 nodes and only 1 root,
and I'm using my own very simple message passing algorithm), and I'd
like the root node to store all the messages it receives overnight.
Is it possible for the root not to be connected to PC during the data
collection period, but would transfer whatever data it receives when
I connect it back to the PC the next day (i.e. the base station would
only be running from the battery power during the data collection
period)? If it is possible, how can I do so?
Thanks in advance.

Azhar
