Re: [cf-dev] install and configure californium in ubuntu 14.04 & impleme

["Kraus Achim (INST/ECS4)" <Achim.Kraus@xxxxxxxxxxxx>]

Hi Maher,

I'm also not sure, how I can help you.
Are you able to install a java-jdk? And maven? 
And are there any reasons to use the aged ubuntu version 14.04?

> in order to measure performance metrics (energy consumption, execution time, ...)

Usually energy and execution time are more considered in "small embedded device",
which doesn't run java and instead are programmed using C (or something similar).

There was an interesting research about the coap-performance, 

https://github.com/eclipse/californium/issues/787
 
which compares C and Java implementations. 
(The basic mislead in that was, that it considers single requests instead of "parallel requests from multiple clients", which would be the domain of californium.)
But anyway, may be you can get some ideas from that research.

If you need more and specific help, I would appreciate, if you open issues on github,

https://github.com/eclipse/californium

it's easier to discuss single issues using that than e-mail.

Mit freundlichen Grüßen / Best regards

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).
