Hello, thank you both for your answers.Now that I know that TinyOS 2 runs on the hardware, I can focus on its source code.

Is there a standard protocol stack (up to ISO layer 3 or even 4) in TOS?No. There are many layer 3 protocols, and some layer 4 protocols built on top of them. For example, TinyOS 1.x, Boomerang, and TinyOS 2.0 all have different collection tree protocols (layer 3). TinyOS 1.x has two: MintRoute and MultihopLQI. The latter is generally more efficient than the former, but only works on nodes with a CC2420 radio (telos, micaz). Boomerang has a slightly modified version of MultihopLQI. TinyOS 2.x has CTP (the Collection Tree Protocol), which is specified in TEP 123.
That's the information I was looking for...up to your explanation, I was randomly browsing through the source trees and the documentation, but you mentioned some things that seems to be good keywords for further research.
The routing principles you talked about seem to be different from e.g. the IP routing, why is that? Is it due to the special situation in ad-hoc wireless networks?
