MANET consists of mobile nodes which exchange information dynamically among them over wireless links. The most important element of MANET is Routing Protocols which are needed to handle dynamic communication and also find route so as to deliver data packets to the correct destination. Performance of routing protocols is an important issue because of dynamic nature of MANET. In this paper performance of DSR and TORA routing protocols is evaluated for FTP based application traffic on IEEE 802.11a WLAN Standard and 24 Mbps data rate. The network performance is evaluated by using OPNET simulator based on various quantitative metrics- Network Load, Throughput, Delay, Download response time, DSR total route replies sent, DSR routing traffic sent and received and Media Access Delay by varying physical characteristics and number of nodes. A comparative performance analysis of these protocols have been carried out in this paper and in the last conclusion will be presented which demonstrate that performance of routing protocols differs by varying the network and selection of accurate routing protocol according to the network ultimately influences the efficiency of the network in a magnificent way
