as far as I am aware LPL is asynchronous. The TEP is here: http://www.tinyos.net/tinyos-2.x/doc/html/tep105.html and tutorials are here: http://www.tinyos.net/tinyos-2.x/doc/html/tutorial/
I have, however, read in the contrib about "synchronous" LPL (rincon) http://docs.tinyos.net/index.php/TinyOS_2.x_index_of_contributed_code#Rincon _Enhanced_CC2420_Radio_Stack ...it appears to use a system of recording neighbour-schedules and times its preambles such that they start just before it thinks the intended recipient is to wake up, thus reducing the length of the preamble required (recipients can ACK a unicast to stop the senders preamble continuing longer than necessary). If you find anything else useful wrt LPL-style synchronous stuff please share! Cheers -Ben > I have recently started working with TinyOS on the micaZ motes.
