摘要：Ad Hoc Networks is a multi - hop wireless network with dynamically changing networkconnectivity owing to mobility. It consists of a collection of wireless mobile nodes it will act without theuse of any existing infrastructure or centralized administration. With this flexibility, networks can beformed anywhere, at any time, as long as two or more wireless users are willing to communicate. Insuch a dynamic network routing is a challenging problem Different routing protocols are designedassuming certain mobility patterns of the mobile nodes in the network. However the choice of mobilitypattern may favor certain protocols over the others. Hence it is necessary to study the performance ofdifferent routing protocols under different mobility models. In this work two mobility models with highmobility and Low mobility constraints have been considered which mirror the realistic mobility patternsof the mobility nodes with high mobility and low mobility. The two reactive protocols AODV and DSRare examined based on the traces derived for each of these mobility models for various speed of themobile nodes, Traffic and Node Density in the network. An analysis of the results obtained from thesimulations shows that the AODV protocols in Boundless Simulation Area model performs better thanDSR. Based on the observations, it is to suggest that AODV routing protocol can be used underhigh mobility since it outperforms DSR protocols
