Re: [lp-wan] C Implementation of SCHC ?

[Hannes Tschofenig <[e-mail]>]

Hi Khaled,

I found those papers searching the web but, given my lack of familiarity with SCHC, I wasn’t sure whether these two papers provide data related to the work being in the drafts or propose extensions to it. At least the titles gave me that impression (layered SCHC and dynamic context for SCHC).

Ciao

Hi Hanna,

we have published the following papers around SCHC:

1- LSCHC: Layered Static Context Header Compression for LPWANs
2- Dynamic Context for Static Context Header compression in LPWANs

Best,
Khaled

Hello Hannes,

I don't know of a SCHC implementation at this time.
The closest I know to an implementation is the RiOT guys intention of adding SCHC to RioT. AFAIK, they were debating whether to rewrite SCHC in C or run micropython over RioT.

Regarding papers, I'm aware of a paper being submitted by S. Aguilar et al. (IMT Atlantique, Rennes and UPC, Barcelona) but I'm not sure what its status exactly is.
I'll let the authors come out of the wood.
A quick search on ieeeexplore with the keyword "SCHC" returned two relevant papers (published this summer), YMMV.
What performance are you interested in ? Compression, fragmentation, .. ?

Best regards

Dominique

Objet : [lp-wan] C Implementation of SCHC ?

Hi all,

I was searching for a C implementation of SCHC and only found Python and JavaScript implementations. Can someone send me a pointer to a C implementation?

I also recall a paper being distributed about the performance of SCHC but I cannot find that either. A pointer would be great.

Thanks.

Ciao
Hannes
