5. CONCLUSION
In this paper we have evaluated the performance of DSDV and DSR routing protocols for ad hoc networks using NS-2.29 event simulator keeping packet size of 512 Byte.DSDV uses the proactive table-driven routing strategy whereas DSR uses the reactive on demand routing strategy with different routing mechanisms. Experimental results showed that DSR perform better for Packet Delivery Fraction as well as Throughput. Also, DSDV apply the sequence numbers and contains one route per destination in its routing table whereas DSR uses source routing and route caches and maintains multiple routes per destination. The other observation from the experiments on DSDV and DSR protocols, with an increase in number of nodes for a fixed area of 500m x 500m illustrates that even if the terrain area of the network scenario is kept constant, the behavior of these routing protocols changes.It has been found that the overall performance of DSR routing protocol for performance matrices, Packet Delivery Fraction as well as Throughput is better than that of DSDV routing protocols. In our experimental evaluation we have taken up comparison of DSR and DSDV protocols with varying number of nodes. We shall consider the comparison of DSR and DSDV by varying packet size and speed of nodes.
