**6. Conclusion**

The performance of all the routing protocol are measured with respect to metrics namely, Packet Delivery Fraction, End to End Delay and Throughput in three different scenarios: simulation time, number of nodes and node speed. The results indicate that the performance of A-AODV is superior to regular AODV and DSDV. It is also observed that the performance is improved, especially when the number of nodes in the network is increased . When the number of nodes is increased beyond 30 and above, the performance of all the three protocols varies very much. It is due to the fact that, lot of control packets are generated in the network. It is also observed that A-AODV is even better than DSDV protocol in PDF, lower end to end delay and throughput. DSDV is better than AODV protocol in PDF. It is concluded that A-AODV improved the PDF and lowered end-to-end delay when the number of nodes are increased. Throughput is also improved. AODV has lower performance compared to DSDV in most of the scenarios.
