Design and investigation of scalable multicast recursive protocols for wired and wireless ad hoc networks

The AODV protocol is one of the most well-known unicast ad hoc protocols. The advantage
of this protocol in comparison to the classical distance vector and link state routing protocols
is that it uses less number of messages because of its reactive nature. Another advantage is
that it is loop free protocol because it uses the idea of sequence numbers for messages. On
the other hand the use of sequence number may cause some difficulties; suppose this
sequence number becomes no longer synchronized or wrapped around which will cause a lot

of conflicts.
