Investigation of Effects of Mobility on Routing Protocols in MANET

The routing protocols are the backbone to provide efficient call services in mobile ad hoc networks, in terms of both performance and reliability. Many routing protocols for such networks have been proposed so far. Amongst the most popular ones are Ad hoc On-demand Distance Vector (AODV), Destination-Sequenced Distance-Vector Routing protocol (DSDV), Dynamic Source Routing Protocol (DSR). This paper presents investigations regarding the performance comparison of the said protocols for varying node mobility in mobile ad hoc networks (MANETs). The simulated results are observed using simulations, using NS-2 simulator. The outcome of the investigation is that reactive protocols perform better than proactive protocols. Further DSR has performed well for the performance parameters namely delivery ratio while AODV performed better in terms of average delay.
