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. With this flexibility, networks can be formed anywhere, at any time, as long as two or more wireless users are willing to communicate. In such a 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 two mobility models with high mobility and Low mobility constraints have been considered which mirror the realistic mobility patterns of the mobility nodes with high mobility and low mobility. The two reactive protocols AODV and DSR are examined based on the traces derived for each of these mobility models for various speed of the mobile nodes, Traffic and Node Density in the network. An analysis of the results obtained from the simulations shows that the AODV protocols in Boundless Simulation Area model performs better than DSR. Based on the observations, it is to suggest that AODV routing protocol can be used under high mobility since it outperforms DSR protocols.

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. With this flexibility, networks can be formed anywhere, at any time, as long as two or more wireless users are willing to communicate. In such a 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 two mobility models with high mobility and Low mobility constraints have been considered which mirror the realistic mobility patterns of the mobility nodes with high mobility and low mobility. The two reactive protocols AODV and DSR are examined based on the traces derived for each of these mobility models for various speed of the mobile nodes, Traffic and Node Density in the network. An analysis of the results obtained from the simulations shows that the AODV protocols in Boundless Simulation Area model performs better than DSR. Based on the observations, it is to suggest that AODV routing protocol can be used under high mobility since it outperforms DSR protocols.
