MANETs are generally classified in three categories namely proactive, reactive and hybrid standardized. Moreover, it is self-organized and self-configured, they does do not depend on any fixed infrastructure, each node in the their network operates as a router that stores and forwards data packet from other nodes, therefore the task of routing is a challenging task in MANETs. The article are interests in reactive and proactive Ad-Hoc routing protocols, it studies the performance of reactive and proactive routing protocol which are AODV and OLSR routing protocols respectively in MANET by different scenario to find out the efficient routing protocol for routing, as well as, we will present a comprehensive performance evaluation study AODV and OLSR routing protocols to understand the nature of the routing protocols performance in different scenarios with variable amount of payload and number of nodes. The article are Focused to simulate the routing protocol AODV and OLSR routing protocols using network simulator-NS2 (ver-2.34). The simulation is done to evaluate and analyze the performance of protocols based on protocol behavior, packet lost, end-to-end packets delay and throughput. The AODV routing protocol is showed good performance in displayed results, it showed maximum PDR, small delay and normalized routing load in low mobility
