Asynchronous low power listening similar to the behavior of B-MAC has been introduced for the CC2420 radio in TinyOS 2.x. This LPL CC2420 stack is not B-MAC or X-MAC, by the way. The 'experimental' version is still located in tos/chips/cc2420_lpl, but a more reliable and robust version can be found in tinyos-2.x-contrib/rincon/tos/chips/cc2420_lpl. That version is going to get a few more features before getting put back into the baseline.
Actually, B-MAC *is* in there, because the heart of B-MAC is the flexible control interfaces to the radio, not exact method of preamble sampling. The preamble sampling, as per the original publication, can be optimized in numerous ways and still be B-MAC, including sending cyclical packets as is done in TinyOS 2.x (see Section 8 of the B-MAC publication). -Joe _______________________________________________ Tinyos-help mailing list [email protected] https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
