EVALUATING PERFORMANCE OF DSDV & DSR ROUTING PROTOCOLS IN MANET THROUGH QoS PARAMETERS

Ad hoc is a network connection method which is often associated with wireless devices. The connection is established for the duration of one session and requires no base station. Instead, devices discover others within range to form a network for those computers. Devices may search for target nodes that are out of range by flooding the network with broadcasts that are forwarded by each node. Connections are possible over multiple nodes known as multi hop ad hoc network. For this ad hoc network I have tested the quality of service parameters like throughput, packet loss and delay for protocols DSDV and DSR with different number of nodes for various counts of agents and sinks. The comparisons have shown that DSR perform better than DSDV on all Quality of Service Parameters when the number of nodes increases, for various numbers of agents and sinks. Network simulators enable us to study the performance and behavior of these protocols on various network topologies. The performance of the network is validated with an NS2 for DSR and DSDV routing protocols.
