DATA DELIVERY PERFORMANCE ALGHORITHMS APPLICABLE TO ( AODV&DSR) ROUTING PROTOCOLS

Abstract

The mobile network is the key features of communication scenario in the real world nowadays. Mobile Ad-hoc Networks (MANET) are the self-configuring networks and they acted without any internal infrastructure. The routing protocols are the deciding factor of the sending and receiving routes. Since the nodes are mobiles, connections in the network can change dynamically and nodes can be added and removed at any time. This research compares the efficiency of two routing protocols Ad hoc On-Demand Distance Vector (AODV) and Dynamic Source Routing (DSR), to judge the critical criteria of performance, for both routing protocols, due to the fact that, data are vital, and important to users and their specific applications, in order to select the most reliable routing protocol, and this decision will be directly effect the level of security, reliability and cost. The performance comparison is carried out by values of performance matrix of PDR (Packet Delivery Ratio), End to End Delay and number of hops. The performance of both the protocols are reported in results. Simulation tool will be OPNET modeler. The performance of these routing protocols is analyzed by three metrics: network load, capacity and mobility. The routing protocols are explained in a deep way with metrics. Comparing AODV and DSR the results can be seen that AODV perform better than DSR in network with varying load, capacity and speed. The DSR performs well compared to the AODV protocols in terms of delay and number of hops.
