Hi there
Sorry for the confusion, I am looking for advise on:
a - How does one detect a collision
b - How does one detect an asymmetric link
I have written code to detect asymmetric links based around multiple timers
that are running at different intervals waiting on packets to be received after
a broadcast, if it does not hear any packets back it will eventually conclude
that it has an asymmetric link.
However, the node may not hear back from a broadcast due to collisions.
I am looking for advise on how you detect a collision?
Thanks
Anthony

what exactly do you mean by collisions on an asymmetric link?

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
