RE: [6lowpan] Fwd: I-DACTION:draft-daniel-6lowpan-load-adhoc-routing-00.txt

Hello Daniel,

I have some comments/suggestions in your new draft: 6LoWPAN Ad Hoc Routing
Protocol(LOAD):

            1) In introduction you say that "the existing AODV protocol is
not suitable for 6LoWPAN", I think that in general case all the MANET
protocols can not be directly applied to 6LoWPAN, since they do not take in
consideration its characteristics (i.e. strong energy limitations);

            2) In the overview chapter you say that your protocol relies on
three routing tables: neighbor, routing and route request. But in chapter 5
you only described the last two tables. Are you not considering describing
the Neighbor Table, just because it is build on MAC layer? 

            3) In chapter 3 you affirm that LOAD cooperation with
hierarchical routing is TBD, but do you think that it will be possible to
merge these two concepts? It seems to me that they present a very different
structure;

               4) How is calculated the link cost, just by "accumulated link
cost from the originator to the destination"? This approach could lead to
bad choices, since a path can have a good energy average but it could
present a node with low energy level.

   6LoWPAN Ad hoc Routing Protocol(LOAD) is intended for use by IEEE 
   802.15.4 devices  in a 6LoWPAN.  It is a simple on-demand routing 
   protocol in the adaption layer for IPv6 packets.
