In this paper, we optimized the performance of Ad hoc on Demand Vector (AODV) and Dynamic Source Routing (DSR) protocols through simulation. Numerical and simulation results presented illustrate how the performance of an ad hoc network protocol drastically changes as a result of changing the mobility model and ambient noise level in the network. The simulation results showed that, in the presence of ambient noise level in the network, AODV and DSR protocols have a significant improvement in end-to-end delay reduction with 68.5% for AODV and 86.8% for DSR respectively. The network load simulation result revealed that DSR protocol maintains a constant routing load while the AODV protocol shows a 75% drop in routing load.
