In this paper we have investigated performance of two reactive MANET routing protocol Ad Hoc On-demand Distance Vector Routing protocol (AODV) and the Dynamic Source Routing protocol (DSR) by using mobility model. Both share similar On-Demand behavior, but the protocol’s internal mechanism leads to significant performance difference. We have analyzed the performance of protocols by mobility and type of traffic (CBR and TCP). A detailed simulation has been carried out in NS2. The metrics used for performance analysis are Packet Delivery Fraction, Average end-to-end Delay. It has been observed that AODV gives better performance in CBR traffic and real time delivery of packet. As a result, more data packets can be received by the destinations in inter-group communications. Hence, the packet delivery ratio is increased as the speed increases. Where as DSR gives better results in TCP traffic and under restricted bandwidth condition. The simulation results reflect that group partitions have a significant impact to the performance of network routing protocols.
