Hi,
If I am not wrong, the algortihms you mention are routing algorithms.
So you must find in which classes (and layers) routing algorithms are implemented in Mixim.
( I assume you are using Mixim for mobility)
And extend those classes for your own aim. May be some of them could be implemented by the Mixim stuff.
Finally, Mixim and Omnet API are the best addresses for an overall view and understanding..
Also, I am a newbee and without reading tutorial and API, it is impossible to understand what to do and how to do..
And, to admit, unfortunately it is a hard work :(
