Mobile Ad-Hoc Network (MANET) is a wireless network without infrastructure. Self configurability and easy deployment feature of the MANET resulted in numerous applications in this modern era. Efficient routing protocols will make MANETs reliable. In this thesis, to find out the efficient routing protocol for routing, we have considered four different aspects scalability, mobility, network load and TCP delay to analyze the performance of DSR, OLSR and AODV routing protocols. HTTP traffic is used over the network designed for our analysis. Performance metrics Throughput and Delay are used for the performance analysis. In our simulation results, none of the protocols we selected have shown best performance in all the four different aspects considered. We conclude the efficiency of a network can be achieved by choosing the best suitable protocols based on the network requirement
