Comparative study of on-demand and table-driven routing protocols in MANET

Abstract

In this paper, we have studied a comparative analysis on three MANET routing protocols namely AODV, DSR and DSDV. The performances of protocols are evaluated with respect to packet delivery ratio, throughput, average end-to-end delay, routing overhead, normalized routing load, and packet drop and loss metrics. Experiments has been conducted with 80 numbers of nodes using random waypoint mobility model for constant bit rate traffic using NS-2.35 simulator as a function of varying speed. Simulation results conclude that the throughput performance of both the on-demand routing protocols is fairly comparable. However, DSR protocol outperforms in terms of routing overhead, normalized routing load and packet drop metrics than AODV. Overall, AODV protocol exhibits superior performance in terms of packet delivery ratio and packet loss.
