Hello Maher,

you need to be a bit more specific with what you need help with.

Installation of californium should be easy if you are using maven (if 
not you are in trouble and I can't help you).

As for running californium, there are some pretty extensive examples in 
the demo-apps folder. For DTLS you can have a look at the 
sc-dtls-example-* folders.

As for comparing authentication algorithms, keep in mind that DTLS does 
much more than just authenticate. It provides encryption, integrity 
protection, replay protection etc. so comparing it to a pure 
authentication scheme might be misleading. Also please consider to have 
a look at DTLS 1.3 (it's not a finished standard yet) which has a much 
better performance than DTLS 1.2 (which is what the Californium module 
Scandium implements).
