Abstract: A Mobile Ad-hoc Network (MANET) is self-configuring network made out of portable nodes with no altered foundation. In a MANETs, there are no distinction between a host node and a router so that all nodes can be source and forwarders of movement. Among all the different protocols unicast will be a standout amongst the most critical application in MANETs which manage the exchange of message from single source to single destination hence this sorts of protocol are extremely powerful and mainstream these days. We have proposed a unicast Routing Protocol for MANETs which consolidate the directional forwarding along largest distance from the single source to single destination, named as AB-URP. The fundamental point of this protocol is low system postponement, accomplishing lessened packet overhead and high adaptability in the system.
