Routing protocols in MANET: Performance comparison of AODV, DSR and DSDV protocols using NS2

A mobile Ad-hoc Network (MANET) become the one of top area of research, due to their simplicity of deployment. No infrastructure is required for nodes to connect with each other in the network, and with out aid of centralized administration. The nodes with MANET are quickly deployable, independent and self repair. Despite these advantages routing protocols suffering from many problems like mobility, synchronization, localization, long route and other while routing. Therefore this protocols should be study in depth, simulated in different conditions and classified. this classification and simulation helps in understanding, comparing performances and assist researchers to differentiate the characteristics and define the pros and cons of routing protocols. A detailed study and simulation model using Network Simulator (NS-2.34) with different traffic models are presented in this paper. The simulation and the performance study will focus on the impact of the network size, average energy consumption per received packet and the network density.
