Dear Ronny,
Interesting work, thanks for publications.

But we did a lot of (unfortunately unpublished)
performance tests
with other EXI implementations on the Zolertia Z1 sensor node, which
showed that the compression of EXI for XMPP messages is high but the
implementation effort and the memory consumption as well. So we
decided to optimize XMPP messages and there behavior in a smart
object network directly to have more available memory for XEPs! This
solution and the implemeted XEPs can be found as well in the
mentioned papers/journal.
Have you tried EXIP? As I checked out ws4d-uexi, I found there are imported sources from
EXIficient (JAVA) -- maybe not a best codebase for embedded use.
In theory (and some of our practices), adequate design of schema and protocols may reduce
required memory for EXI down to less than 10 kBs.
If you have interest, some of ideas may be found in the following paper.
