Answer 1

A routing table entry which maintains reverse path is removed after a time out interval. This time out should be long enough to allow PREP(Route Reply) to come back.

A routing table entry which maintains forward path is removed if not used for active_route_timeout interval.

Time out used in AODV are :

i) active_route_timeout

A routing table entry which maintains forward path is removed if not used for active_route_timeout interval.
