A mobile ad hoc network (MANET) consists of mobile wireless nodes and is an infrastructure less and decentralized network which need a robust dynamic routing protocol. 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 randomly. The mobile nodes can receive and forward packets as a router. Routing is a critical issue in MANET and hence the focus of this paper is the performance analysis of routing protocols. Many routing protocols for such networks have been proposed so far to find optimized routes from source to the destination and prominent among them are Dynamic Source Routing (DSR), Ad-hoc On-Demand Distance Vector (AODV), and Destination- Sequenced Distance Vector (DSDV) routing protocols. The performance comparison of these protocols should be considered as the primary step towards the invention of a new routing protocol. Over the last decade various routing protocols have been proposed for the mobile ad-hoc network and the most important among all of them are DSR, DSDV and AODV. This paper presents a performance comparison of proactive and reactive routing protocols DSR, DSDV and AODV based on mobility model and QoS metrics (packet delivery ratio, average end-to-end delay, throughput, and jitter), normalized routing overhead and normalized MAC overhead by using the NS-2 simulator. In this work, the performance comparison is conducted by varying mobility speed, a number of nodes and data rate. The main objective of this paper is to compare the performance of all the three routing protocols and then to make the observations about how the performance of these routing protocols can be improved. Performance of these routing protocols are compared on the basis of various parameters such as throughput, delay and packet delivery ratio. The comparison results show that AODV performs optimally well not the best among all the studied protocols.
