  abstract = {Ad hoc networks are characterized by multi-hop wireless networks with frequently changing network topology and lacks predefined infrastructure. The mobile nodes are wireless and following some predefined mobility pattern and using some propagation model and are efficiently connected to form an autonomous system. However, the network is dynamic in nature thus there is no restriction on the nodes and have complete freedom to join or leave the network. In this network, any change in network should be completely migrated across the network in quick time. In this research paper, the performance
of two prominent non-fading propagation models – Two Ray Ground and Free space propagation models are compared under on-demand routing protocols for mobile ad hoc networks—Ad Hoc On-Demand Distance Vector Routing (AODV). The
performance of AODV is tested under Random Waypoint Model (RWP) and Random Direction (RD) Model using Network Simulator-2 (NS-2). We demonstrated that even though Two Ray Ground and Freespace propagation models share few
similar behaviors, but the differences in the propagation mechanics can lead to significant performance differentials. The performance differentials are evaluated and analyzed using varying network size, topological area, transmission range, network load, mobility and pause time. Based on the observations, the conclusion and recommendations are given about
how the performance of both propagation models and protocol can be improved.},
