AODV Route Discovery and Route Maintenance in MANETs

An Adhoc network is self configuring, self organizing, and infrastructure-less network without any centralized administration. In networking (wired and wireless), routing has been one of the important function we need to concentrate. Routing is the process in which, we will be sending the packets or messages from the source to the destination. In this paper, we will discuss on AODV (Adhoc On-demand Distance Vector) Routing Protocol which is a reactive protocol and it will create the route on-demand. In AODV, there are three types of messages that will govern the working process. They are RREQ, RREP, RERR messages. Here, we will discuss the functioning of AODV and how the process of route discovery and route maintenance takes place.
