Hello,
In tinyos-2.x we can set the global radio power of CC2420 by defining
the CC2420_DEF_RFPOWER to a different value or
we can change it dynamically on a per-packet basis using the setPower
command from the CC2420Packet interface.
How do I change the radio power for Packet Acknowledgments
Hello all,
To prevent duplicate packets you would look at the origin and sequence number.
This would then assume that you maintain a list of packets from every origin
meaning probably memory problems, and possibly speed inserting new/checking
duplicates.
My question is what data structure are
Hi Guys,
If you are thinking of writing a radio driver for a new radio chip,
then I will be more than happy to help you out with that. I think the
RF2xx driver is robust enough that with by rewriting the backend you
will get all features (LPL, TimeSync, BLIP) automatically.
Best,
Miklos

Hi,
I don't know, but I'm thinking in loud.
If you are using HW ack - it is probably impossible.
So - you need to use SW ack.
No more thoughts :)

Hi,
Perhaps you should consider a sliding window mechanism, TCP style.
BTW - how can you receive duplicate packets? The only reason I see - it can
happen when the sender didn't receive the ack, although the receiver did
send it. In this case, the sender will send the again the same packet.

Hi all,
I am using Deluge T2 with telosb motes. I would like to make my program's
code suitable for Deluge T2 because now it does not properly answer to
Deluge commands. The question is : Which differences must have an
application to work with Deluge T2?
I have seen the differences between Blink
Hi all,
As I am new to the WSN simulation environment I need a document comparing
the different simulators to have a quick overview on all the tools to be
able to choose the suitable one for me. I can't find such a comparison; so
anyone can help me in getting one?

Hi All,
We recently observed an unexpected behavior of the CC2420 radio on MICAZ.
I wonder if you had similar experience and any insights to this problem.
We scheduled a timer to turn on CC2420 at a specified time. The radio, however,
was turned on more than 200ms later than the specified time.
I am wondering whether you programed the directly connected node as the base
station (otherwise, it doesn't accept commands from the serial port). It
doesn't seem that you did because you commented out CFLAGS +=
-DDELUGE_BASESTATION in your makefile.

Hi,
I am using TinyOS1.x on a MICA2 node.
I would like to determine the current date and time and send it either over
the Serial forwarder or over the radio. How do I determine the current
date/time on TinyOS1.x?
Thanks,
Suresh
