[Tinyos-help] Data rate problem in TinyOS

[Ryan Aures]

Hello all,

We have been testing the Tmote Sky motes to see what is the maximum
achievable data rate, and have gotten very discouraging results.  Of the
250kbps that is supposed to be possible, we are only getting reliable
transmission up to about 50kbps.  Beyond this we start dropping packets, and
can not get anywhere near 250kbps.  We think the problem is on the
transmission end, but it is difficult to tell where packets are being
dropped, and what is happening at the radio.  Is this a radio problem, a
TinyOS problem, something else...?  It seems like several people have
encountered this problem, does anyone know what is really happening here?
We have also tested the beta release of TinyOS 2.0 but there seems to be no
improvement.  Any advice would be greatly appreciated.

Thanks
