A Mobile Adhoc NETwork (MANET) is a self-configuring network that can have an arbitrary topology along the time. Each mobile host works as a router and it is free to move randomly and connect to other hosts arbitrarily. Thus, the network topology can change quickly and unpredictably since there may exist a large number of independent ad hoc connections. The default mechanism of route discovery in MANETs is flooding. The routing overheads caused because of broadcasting are a bottleneck in performance of AODV protocol. In this paper, improved AODV protocol is proposed, analyzed and implemented that follows an efficient method of route discovery which adjusts itself dynamically based on the network density of MANET.
