[Olsr-users] Hop Count of data packets

I had not considered this. Thanks for the suggestion.

This hop count has to be done by a "mesh monitoring" work station (mesh
nodes are embedded devices and there is a PC which monitors the mesh
nodes. The PC needs to be able to able to trace the path) 

I think that should work.

Maybe I misunderstood you now but what you can do is simply traceroute  
and count the number of hops your data takes.
What would be wrong with that idea? Did you already consider it?
