[Battlemesh] tests for WBMv3

[Luca Tavanti]

Hi Elektra,

Thanks for the quick reply :)

Yes, ping could be a useful tool for generating simple traffic and collecting statistics.

As for running two protocols at the same time, it has pros and cons.
You indeed let them work under the same environment, but, what if you want to compare three or more protocols? Set up a sort of tournament?
Also, how can you be sure that the protocols do not disturb each other? Especially when you increase the load, this is not such a remote possibility... 

Finally, can I ask you how you plan to measure overhead?

Cheers,
Luca
