You need to take a look at the different adhoc-routing agent
implementations. For example in DSDV, DSDV_Agent::diff_subnet() checks for
packets outside its own subnet and fwds them to the base_stn. so all
pkts destined to addresses outside its own subnet is dropped in yr case,
as pkts are not cached incase route to base-stn is not known.
so you would need to add some mechanism to the adhoc routing agent for
supporting hier-routing (incase no base_stn nodes are available).
