Performance Analysis of Proactive and Reactive Routing Protocols for QOS in MANET through OLSR & AODV

A mobile ad hoc network (MANET) consists of mobile wireless nodes. The communication between these mobile nodes is carried out without any centralized control. MANET is a self organized and self configurable network where the mobile nodes move arbitrarily. The main classes of MANET routing protocols are Proactive, Reactive and Hybrid. In this paper we compare performance of Proactive routing protocol by focusing on Optimized Link State Routing (OLSR) and Reactive Routing Protocol by focusing on Ad Hoc On Demand Distance Vector (AODV). In this paper our simulation tool will be OPNET modeler. The performance of these routing protocols is analysed by three metrics: delay, network load and throughput.This paper presents a performance analysis of two Mobile Ad Hoc Network (MANET) routing protocols- AODV and OLSR. For the behaviour simulation and evaluation of these protocols we used the OPNET Modeler simulation tool. Each routing protocol was configured into two network scenarios with the default and modified parameters in order to achieve better transmission characteristics. The final evaluation ispresented at the end of this paper .
