Re: [ns] ad-hoc protocols simulation

[sameer tilak <sam_tilak@yahoo.com>]

Hi,
If I am not mistaken, target_ you have mentioned about
is nothing but a connector(NSObject). In case of
connector it is assumed that the node has only one
neighbour. So in this case during the connection set
up the target_ is set to the neighbour of the given
node. Thus send(p, h) does the target_->receive(..) it
basically calls the receive of its neighbour.

This might help you.
