SIMULATION AND COMPARISON OF AD HOC NETWORKS ROUTING PROTOCOLS BASED ON OPNET

Abstract

Ad-hoc routing algorithm has always been a core problem in research of ad-hoc networks. In order to be able to deal with various routing protocol problems on an ad-hoc network like poor validity and large control overhead, this paper classify and compare ad-hoc network routing protocols through OPNET simulation tool and focus on testing two routing protocols' performance namely, table-driven and on-demand routing protocol. The Destination Sequenced Distance Vector routing protocol is the most used table-driven routing protocols, While AODV and DSR routing protocols are the two most used on-demand routing protocols. The performance of these three protocols is simulated with a variety of packet delivery functions, average end-to-end delays, and routing loads. These protocols are also analyzed and compared. The simulation results show that for a high mobility environment, the on-demand routing protocol is the best option.
