Backgrounds/Objectives: Mobile Ad hoc Networks (MANETs) uses mobile nodes which exchange information dynamically over wireless links. Routing Protocols are the most vital element of MANETs, which are needed to handle dynamic communication and also find route. Performance of routing protocols is an important issue. In MANETs, due to mobility of nodes, the wireless links are highly error prone and can go down frequently, interference and less infrastructure. The nodes are usually mobiles in MANETs. Methods/Statistical Analysis: This research work is carried out to compares the efficiency of two of the on-demand routing protocols Dynamic Source Routing (DSR) and Temporally Ordered Routing Algorithm (TORA) based on its performance. Findings:The performance of these two protocols is measured by values the of performance matrix of PDR (Packet Delivery Ratio), Throughput, End to End Delay, Routing overhead and Energy Consumption. These metrics are measured by simulation time using mobile nodes. Based on the simulation time, the performance of both the protocols are analyzed and resulted via its simulation results.Applications/Improvements: The other protocols likeWRP for FTP, TELNET and CBR are analyzed and compared in future to find the performances. Also, some of the hierarchical routing protocols are considered to measure its performances.
