Performance Evaluation of AODV and AODV-LR in terms of Route Maintenance

The Idea at the back of ad hoc network is multi-hop broadcasting in which packets are sent from the source node to destination node. It does not have any infrastructure based network. In ad hoc network distributed routing is available. Because of mobility in nodes, there are recurring path breakages. In ad hoc network, the primary goal of routing is to detect paths between source to destination with minimum routing overhead. Applications of ad hoc network are military applications as well as emergency operations. In ad hoc networks this work focused on AODV route maintenance. This paper suggests a new approach of route maintenance scheme AODV-LR in AODV which reduces the data transmission time of AODV as well as makes better performance with minimum bandwidth utilization and maximum packet delivery ratio. This concept has been implemented and tested on OMNet++.
