You don't need to do that. If you are measuting hops, you can just trace the packets by their IDs and increment the hop count as necessary (which is what I'd do in tests with actual nodes). Since you are using TOSSIM, you can print a time string from the simulator if you wish to measure time, and not hops. But as synchronizing is not the easiest thing in life, hop counts are a much simpler and no less reliable way to evaluate the average delay than delay itself. (Of course, if you wish to relate hop count x time, you can do both and get an average delay per hop).
