[ns] aodv route discovery

["K.R. Anupama" <anupkr@bits-pilani.ac.in>]

hi!
  I got very strange results when i tried simulating AODV. i smulated the
protocols on three nodes 0,1,2. intially node0 transmits data through
node1 to the destn node after the route discovery process. then
aftersometime node1 has to start transmission to node2, but it once goes
through the route discovery procees. why should it do so  when the route
to
node2 is already active .there has been no movement betwee these two
transmissions .
does the router trace also show the excahnge of hello packets.
