Background and Objective: Mobile ad hoc networks require routing protocols to discover routes between nodes, which is challenging due to unpredictable network environments. Over the years, different versions of the conventional routing models have been proposed, but still proficient routing is quite essential. This paper examined DSR (dynamic source routing), a well-known routing protocol in mobile ad hoc networks for possible improvements. This study determined a comparative performance analysis of the standard and revised routing models of the DSR. Materials and Methods: These analyses were performed using NS-3.25 (Network Simulator, version 3.25) and with the help of various performances evaluating metrics such as the throughput, PDR (packet delivery ratio), EED (end to end delay), PL (packet loss) and NRL (normalized routing load). Results: Average numerical values of different performance evaluating metrics of either routing models of the DSR were obtained for different network node densities from the simulation results. Performances of the standard and revised dynamic source routing models were evaluated and compared through the graphs. Conclusion: This study concluded performance improvements in the revised DSR routing model as compared to its standard version for different node population scenarios.
