Performance Comparison of DSR, OLSR and FSR Routing Protocols in MANET Using Random Waypoint Mobility Model

Abstract

The Mobile Ad-hoc Network (MANETs) is a dynamic network in which collection of mobile nodes forming a temporary network without any infrastructure, centralized access point, or central administration. It allows wireless nodes to communicate with each other in the absence of any centralized support. In this kind of scenario any node can move from place to another in an arbitrary manner and hence topology gets change very frequently. Because of this dynamic geographical arrangement the link instability and node mobility make routing a core issue in MANETs. Some appropriate routing mechanism is required to manage the successful deployment of MANETs. This paper presents the performance analysis of two proactive routing protocols OLSR and STAR. This simulation study was conducted by using the QualNet 5.0.2 simulator. Performance analysis of OLSR and AODV is evaluated on the basis of three performance metrics Average Jitter(s), Average-End-To-End Delay (s), and Throughput (bits/s). The simulation results clearly indicate that the OLSR routing protocol is clearly outperforms STAR routing protocol.
