Mobile ad hoc networks (MANETs) are one of the fastest growing areas of research. They are an attractive technology for many applications, such as rescue and tactical operations, due to the flexibility provided by their dynamic infrastructure. In the current study we have compared the performance of three MANET protocols AODV as reactive, OLSR and TORA as proactive using random walk model and random way point models.These share some similar behavior, but the protocols internal mechanism leads to significant performance difference. We have analyzed the performance of protocols by varying network mobility and type of traffic (CBR, VBR and TCP). A detailed simulation has been carried out in OPNET. The metrics used for performance analysis are Throughput, Network load. Random Way Point mobility model for most of the MANET routing protocols give better performance than Random Walk Mobility Model.
