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 happenning by TOSBase..
I will experiment out the idea that you have put and reply you back with the result.

I 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 constantly sending out messages, I would expect node 1 to have to receive and then transmit the forwarded message, which would probably result in less than half the throughput compared to a singlehop setup.A new CC1000 radio stack (back-ported from TinyOS 2.x) is available in the TinyOS 1.x CVS under /contrib/rincon/tos/lib/CC1000. This stack is 21% faster even at the same baud rate - 2324 bytes/sec. I didn't include any time sync interfaces in it, but it works great on my multihop networks. It should drop in place of anyone's current stack so long as they include the correct directories at compile time.-David-----Original Message-----

Subject: [Tinyos-help] Maximum datarate on CC1000 radioHi all,I am working on packet loss and delay measurements. The fact is i need to do this on multi-hop, for which i need to fix the datarates. It seems that when the application is sending 300 packets/minute, out of which i get around 5.2% loss. The node nearer to the base station has 0% loss.My network chosen was..0 -------- 1---------------2
The measurements were done on mica2 mote. Also i observed that as the number of motes increased in the range, losses also increased.. Anyone who know the cause or what might be the datarate for which there will be no loss, please let me know..Thanking you,venkatesh.S
