Power Control and Performance Comparison of AODV and DSR Ad Hoc Routing Protocols

A technique is proposed to evaluate the effect of ambient noise and path loss have on received signal strength of mobile node in a mobile ad hoc network environment using optimized network (OPNET) simulator while comparing the performance of Ad-Hoc on demand distance vector (AODV) and dynamic source routing (DSR) protocols. 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 power control system of the network. The simulation result for DSR and AODV showed a significant improvement with 86.8% decrease in end-to-end delay (sec), while AODV also showed 68.5% drop in end-to-end delay. The network load simulation result revealed that DSR protocol maintained a constant load while there was a 75%drop in routing load for AODV protocol. The simulation results of AODV and DSR routing protocols showed 99%and 98%confidence intervals respectively.
