Mobile Ad Hoc NETworks (MANETs) can make dynamic changes in topology. The most realistic characteristic which differentiates MANETs from other networks is that it is capable of changing its location. The result of the surveys over the last 5 years, show that it can overcome the two difficulties such as congestion and communication between nodes. Different routing algorithms are used while maximizing Packet Delivery Ratio (PDR), throughput and minimizing end to end delay, routing load to improve the performance. Maximum PDR and throughput gives best performance. This paper describes the performance of the three routing protocols in case of change in traffic, no. of nodes and node mobility. To analyze the performance, reactive and proactive routing protocols are considered.
