Study and Comparison Performance of On-demand AODV and DSR, along with the traditional proactive DSDV Routing Protocols for MANET

In wireless research area, efficient routing algorithms can provide remarkable benefits in Ad-hoc networks, including higher throughput, lower average end-to-end delay, less number of dropped data packets and generally an ameliorated network performance. Many routing protocols for such networks have been proposed so far. My research work, an attempt has been made to compare the performance of three prominent on-demand reactive routing protocols for mobile ad hoc networks: DSR and AODV, along with the traditional proactive DSDV protocol. A simulation analysis with MAC and physical layer models is used to study interlayer communication and their performance implications. Experimental results obtained, showed that the On-demand protocols, AODV and DSR perform much better than the table-driven DSDV protocol. Although DSR and AODV share similar On-demand behavior, the differences in the protocol mechanics can lead to significant performance differentials. For a variety of scenarios, as characterized by mobility, load and size of the ad-hoc network were simulated. The performance differentials are analyzed using varying network load, mobility pattern, and Network size.
