Performance Evaluation of MANET Routing Protocols Using Random Waypoint Mobility Model

A Mobile Ad-Hoc Network (MANET) is a self-configuring network of mobile nodes connected by wireless links, to form an arbitrary topology. The nodes are free to move randomly. Thus the network's wireless topology may be unpredictable and may change rapidly .Due to varying mobility characteristics; there is a significant impact on the performance of the routing protocols. There are various Mobility models to generate mobility patterns. In this paper we considered three MANET routing protocols namely DSDV, DSR and AODV.We have compared the performance of protocols by varying Speed parameter with CBR traffic source and by using Random Waypoint mobility model. The comprehensive analysis has been carried out using NS2 simulator. The metrics used for analysis are Packet Delivery Ratio, Average end-to-end Delay and Normalized Routing Load. It has been observed that, under Random Waypoint mobility model, AODV and DSR performs better than DSDV in terms of PDF. However in terms of Average end-to-end Delay, DSDV appears to be the best one.
