A Mobile Adhoc Network is a multihop self-configuring network without any fixed infrastructure of wirelessly connected devices. Due to node mobility and, dynamic topology, designing and implementing reliable routing in MANET is a major challenge. This paper provides the comparative performance analysis of DSR, AODV and DSDV. Different types of test scenarios have been designed with fixed number of nodes and varying mobility. The experimental results have been analyzed and recommendations based on the obtained results have been proposed about the significance of each protocol in different scenarios and situations which will help the researcher in the field to select best protocol under predefined conditions with varied mobility. Furthermore, based on the learning from comparative performance analysis, some modification to AODV route discovery process has been proposed and evaluated. The proposed changes have made significant improvement both in throughput and packet delivery fraction.
