I would be able to do a comparative analysis of two methods as soon as I understand the mechanism described in draft-bormann-6lowpan-ghc. I have already spent a couple of hours trying to understand draft-bormann. At the moment, I cant figure out how the compression mechanism (Section 2) works and how was it applied to the examples listed in the draft. I suspect the draft does not have sufficient level of explanatory text at the moment.

It seems most of the gain will be from compressing out prefixes and zeros, which ghc should handle quite well. -- Jonathan Hui On May 18, 2011, at 10:59 AM, Mukul Goyal wrote: > Hi all > > Fragmentation of RPL control messages has emerged as one of the key concerns > when RPL is run over IEEE 802.15.4 networks.
