The Ad-hoc On-demand Distance Vector (AODV) routing protocol is described in RFC 3561. The philosophy in AODV, like all reactive protocols, is that topology information is only transmitted by nodes on-demand. When a node wishes to transmit traffic to a host to which it has no route, it will generate a Route REQuest (RREQ) message that will be flooded in a limited way to other nodes. Mobile Ad-hoc NETworks (MANETs) are autonomous and decentralized wireless systems. MANET is a collection of mobile nodes in which the wireless links are frequently broken down due to mobility and dynamic infrastructure. Routing is a significant issue and challenge in ad hoc networks. Many Routing protocols have been proposed so far to improve the routing performance and reliability.
