You might want to look at: TYMO (http://tymo.sourceforge.net/) for 1-1 routing 6lowpan (tos/lib/net/6lowpan in TinyOS CVS) for "compressed" IPV6 over motes
There are many sensor network transport protocols (although not TCP) that transfer bulk data. Most of them are designed to run on collection type scenario. Unfortunately, most of them might still be research code used in one specific setting and probably not in a ready-to-be-used-by-others state so you would have to google, email the authors, and hack a bit yourself. - om_p On Jan 16, 2008 2:03 AM, David <[EMAIL PROTECTED]> wrote: > Hi list. > > TinyOS 2.x introduces the Dissemination and Collection algorithms. > > What I would like is a way for the Basestation to communicate with a > single mote (preferably 2-way) over multi-hop.
