AODV (Ad Hoc On Demand Distance Vector)

combination of DSR and DSDV.
Route discovery and maintainatance from DSR.
Hop-by-hop, sequence number and periodic updates from DSDV.
Rreq packets contains last known sequence number for destination.
When a node recives a Rreq for a destination it has a route to, it generates a Rrep with the updated sequence number and number of hops.
Each node that forwards the reply back to the originator creates a forward path to the destination.
