-Wireless networks have gained momentum in the recent years due to the wide range of emerging applications. Among the available wireless networks, Mobile Ad Hoc Network (MANET) offers unique characteristics and application scenarios that create a great research attention recently. Designing an efficient and robust routing protocol is a challenging task and crucial to the core network operations owing to the dynamic properties of the MANET. The scalability is the major challenging scenario in protocol evaluation as the performance is affected on the escalation in the number of nodes and resources. The routing protocols must deliver the better scalability in varying number of mobile nodes in the network. The comparative performance analysis of seven MANET routing protocols such as AODV, DSR, LAR, DSDV, OLSR, FSR, and ZRP are evaluated using network simulation tool ns2. The network simulations using ns2 attempt to provide evidence for the effectiveness of a routing protocol under a wide range of network environments, and it plays a prime role in providing a virtual view of the real application scenario. Considering the significance of routing performance, this research work evaluates routing performance of proactive, reactive and hybrid routing protocols under various simulation scenarios to obtain the exact performance useful for different network conditions and application scenarios. This process analyze the scalability of routing protocols and demonstrate the suitability of routing protocols to different network environments. By considering the results under dynamic network topology, this work can determine the robust as well as most suitable protocols to the ad-hoc network environment. To accurately mimic the realistic context in simulation, the proposed work models the routing protocols in various simulation parameters Keywords – MANET,ns2,AODV, DSR, LAR, DSDV, OLSR, FSR, and ZRP
