Yes, that is correct. Take a look here:

I would just say that it should be large enough, so that the nodes do not drop packets, which would mess up your simulation results. Unless you would like to test whether the queue of the nodes can handle the received packets without dropping them, I would suggest that you use a large enough queue size.
