The Mobile ad hoc network is a self configured and self organized network. The routing of packets inside network is one of its key issues. Many routing protocols have been proposed and analyzed since last fifteen years. This paper presents the analysis of MANET routing protocols OLSR and TORA. This evaluation is achieved by simulations in Optimized Network Engineering Tools (OPNET) with respect to performance metrics i.e. control traffic overhead, end-to-end delay, network throughput and network load. By comparing OLSR and TORA through simulations, our results specify that OLSR performance is better than TORA in terms of the metrics above. OLSR has lower control traffic overhead, higher throughput, higher load and shorter end-to-end delay as compared to TORA. OLSR maintained consistent routes which brings shorter delays. Node mobility affects negligibly on OLSR whereas it affects slightly to TORA. But in general, this difference is not obvious in our simulations. The simulation results also prove that OLSR is more reliable and efficient than TORA.
