Hello, 

Unfortunately there is no 'one size fits all' answer to your question.
The HELLO messaging scheme (periodic, adaptive?) and its parameters are a 
protocol design choice, just like in any protocol such as AODV etc.

Of course, if you assume a periodic hello scheme with advertisements every 
N seconds, then the control overhead can easily be computed as a function 
of # nodes and simulation duration. But what is equally important (and 
cannot be directly inferred) is how many encounters are 'missed' in 
comparison to the current idealized implementation. 
Let me know if this aspect is stg you want/need to explore in depth, if so 
i can make some suggestions on various ways to do it.

hope this helps

Could you please tell me the size and frequency of transmission for these 'hello' messages in a real implementation?  It would be of great help for calculating the control overhead in my simulations.
