RE: [Tinyos-help] Maximum datarate on CC1000 radio

Title: Message 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

The backoff on the mica2 doesn't seem to be as reliable as one would like. I have a little bit about it in the ACK/reliability report I just ref'd. You may also have hidden node problems, where packets collide because two transmitters cannot hear each other. MS venkatesh s wrote: Hi all, I

Thanksfor your kind reply Phil and Michael... What about if i make the nodes to communicate in a single range, and force them to come on hop., which means there shouldn't be hidden node problems.. I did the following to achive the above, for the 3 node network.. Node 2 was forced to receive

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
