Abstract—Ad Hoc Networks is a multi - hop wireless network with dynamically changing network connectivity owing to mobility. It consists of a collection of wireless mobile nodes it will act without the use of any existing infrastructure or centralized administration. In this dynamic network, routing is a challenging problem Different routing protocols are designed assuming certain mobility patterns of the mobile nodes in the network. However the choice of mobility pattern may favor certain protocols over the others. Hence it is necessary to study the performance of different routing protocols under different mobility models. In this work the two mobility models Probabilistic Random Walk and Boundless Simulation Area with high mobility and Low mobility constraints have been considered. The two reactive protocols AODV and DSR are examined based on the traces derived for each of these mobility models for various mobility speed, Traffic and Node Density in the network. The simulation result shows that, in probabilistic Random walk model, AODV yields good performance for high/low mobility, high/low traffic and sparse/dense networks. In Boundless simulation area model the performance produced by both the protocols are almost same.
