Vehicular Ad hoc network (VANET) is an exclusive part of MANET in which collection of mobile nodes that are randomly located so that the connections between nodes are dynamically changing. In VANET mobile nodes form a temporary network without the use of any existing network infrastructure or centralized administration. A routing protocol is used to find routes between mobile nodes to facilitate communication within the network. An extensive range of routing protocols for VANETs has been proposed by researchers to overcome the limitations of routing protocols. In this paper we perform & evaluated the performance of OLSR (Optimized link state routing) protocol using Random Waypoint mobility model (RWP) and Reference Point Group Mobility Model (RPGM). The simulation is performed by using network Simulator. Performance of OLSR is evaluated based on Average end to end delay, Packet delivery ratio, Normal Routing load and Throughput for the different pause time.

Keywords: Random Waypoint, Reference Group Mobility Model.
