Hi,
I just checked TossimPacket.nC on CVS. It seems that the support for getting
RSSI has been provided. I was able to trace the source code. But, when I try
to access, metadata, I get zero value.
I tried printing, (*bufPtr).metadata[1];
Note : My metadata[0] is tx_power.
Any help ? Please corre
Hi Vijayant,
When a mote m1 sends a packet to another mote m2, and m2 replies with an
ack, the ack will most likely be sent with the default tx power
programmed on m2. So if you send a packet from m1 to m2 with your own
power, and you program the simulation to let the other mote respond with
the s
Hi,
I referred to the data sheet. The data sheet says that programmable
output power range is -24 to 0 dBm (in steps of 3). There is no
mention about reverse link gain. Do we have straightaway assume that
it is less than that of tx ?
How do I model reverse gain ? I am a bit confused.
Any help is

Hi,
I think I made a mistake by creating a new function. I should have modified
existing send function of TossimpacketC. Then i would just call AMsend.sendetc..
Please correct me if I am wrong.
Any help is greatly appreciated.
Thanks,
Vijayant

Greg is correct TOSSIM doesn't support any of the CC2420 interfaces.
TOSSIM doesn't support changing the power levels. However you can simulate
networks with varying densities, link qualities, etc. This is done via
altering the link gain model you feed into TOSSIM. Determining what link

I would like to thank Greg for his quick reply. Right now, we don't have
real motes. Our plan is to get things working on TOSSIM (i.e. some kind of
simulation environment) for testing our protocol. We have already developed
Neighbor Discovery protocol and Routing protocols. We just need to give

I remember phil pointed out that radio specific interfaces are not supported
by tossim by packet level interfaces are. He also said that

Hi,
First of all I would like to thank Kevin for his help.
CC2420 directories were indeed missing in .platform file. I added all the
CC2420/* directories to sim/.platform file. But still, I am facing the same
kind of errors.
mkdir -p build/micaz

I don't think getting the latest code will help you any. I haven't

I responded to this on a different thread also posted by Vijayant that
was very similar to this one. This one doesnt show that he is trying
to use TOSSIM though. I assume they are the same problem though

Hi,
I updated all the CC2420* files and dumped in /opt/tinyos-2.x/tos/chips/cc2420/

Sounds bad.
I'd start with a fresh checkout o

Hi,
Still getting the error? The interface definition should be in:
/opt/tinyos-2.x/tos/chips/cc2420/CC2420Packet.nc (at least that's
where it is on my system). If that file doesn't exist, try getting
a newer version of TinyOS (eg. updating cvs).
Cheers,
