Mobile Ad hoc Networks (MANET) are wireless networks where communication of nodes takes placevia radio waves. Due to dynamic topology and mobility of nodes frequent path failure takes place which in return affects the Quality of Service (QoS) in MANET. This paper mainly focuses on the experimental analysis on different propagation models namely Two-ray ground reflection, Free Space and Shadowing models on AODV and DSDV. We have done rigorous experiments to verify the effects of various propagation models and try to find its environment suitability. The QoS parameters we have used for the observation of the performance are throughput, delay and Packet-Delivery-Ratio (PDR). Simulation is done using NS-2.Free Space model gives better performance in both the protocols in contrast to other models. This paper will be helpful for researchers, students who are newly involved in research for better understanding and utilization of propagation models in corresponding environment.
