Mobile Ad hoc NETwork (MANET) is an organization of static and wireless mobile nodes having no any central administration and fixed infrastructure. In MANET, each node can acts as routing and hosting device. Performance comparison and analysis has been conducted by using four different scenarios in NS2 (Network Simulator) for which two reactive (AODV, DSR) and two proactive (OLSR, DSDV) ad hoc routing protocols have been selected by utilizing 802.11 Mac layer. The main goal is to find out the better performing protocol by measuring three metrics Packet Delivery Ratio, Throughput and Routing Overhead. As the results show that the performance of reactive protocols is better than proactive protocols.
