DSR Optimizations
n piggy-backing data onto route discovery to reduce latency
if node that is not target replies to route request, special attention is
needed to make sure that the data is forwarded to final destination
n reflecting shorter routes
usually, as nodes move closer, they will also move out of range in
existing route, so route maintenance will take care of this
alternatively, run network interfaces in promiscuous mode, listen
to who is in your neighborhood and see whether routes in cache
can be shortened
