A mobile ad hoc network (MANET) is a network consisting of a set of wireless mobile nodes that communicate with each other without centralized control or established infrastructure. Every node in MANET moves arbitrarily making the multi-hop network topology to change randomly at unpredictable times. There are several familiar routing protocols like DSDV, AODV, DSR, and OLSR which have been proposed for providing communication among all the nodes in the network. This paper presents Qualitative and Quantitative Analysis of Reactive and Proactive Routing Protocol Performance Evaluation in Mobile Ad Hoc Network for protocols such as OLSR, DSDV, AODV and DSR based on metrics such as security, multicasting, Packet delivery ratio and average end-to-end delay, Routing load by using the NS-2 simulator. The results shows that there is no routing protocol in the current stage without modifications that can provide efficient routing to any size of network, regardless of the number of nodes and the network load and mobility. AODV shows better performance than DSDV, OLSR, and DSR.
