[Tinyos-help] Detecting collisions over asymmetric links

[Anthony Smee]

Hi there

Does anyone have any advise on the best way to detect a collision over an asymmetric link. I have managed to put something together, under TOSSIM, using multiple timers to try and detect asymmetric links. However it does not really deal with collisions, and so the code works, and then sometimes it does not which I put down to collisions I would prefer to be able to detect this and deal with it accordingly.

Also along the same lines, does anyone have any advise on getting a consistent environment in TOSSIM? I have set the gain to be equal for every node's relation, and also a consistent noise but still my results differ with each run.

Thanks

Anthony
