Performance Comparisons Using Routing Protocols with OPNET Simulator in Mobile Ad Hoc Networks

In this paper performance comparisons of mobile ad hoc network's protocol with its quality of service factors has been measured. It is seen that mobile ad hoc networks will be an integral part of next generation networks because of its flexibility, infrastructure less nature, ease of maintenance, auto configuration, self administration capabilities, and costs effectiveness. This research paper shows comparison within mobile ad hoc networks' routing protocols from reactive, proactive and hybrid categories. We comprehensively analyzed the results of simulation for mobile ad hoc routing protocols over the performance metrics of packet delivery ratio, end to end delay, media access delay and throughput for optimized link state routing, temporary ordered routing algorithm and ad hoc on demand distance vector protocol. In mobile ad hoc networks, mobile nodes must collaborate with each other in order to interconnect, organize the dynamic topology as mobility cause route change and establish communication over wireless links. Our simulation results show the lead of proactive over reactive and hybrid protocols in routing traffic for dynamic changing topology. Proactive protocol optimized link state routing, a protocol for building link tables for ad-hoc networks, can transmit traffic more rapidly though involve less processing speed in packet forwarding.
