Mobile Ad Hoc Network (MANET) hasrecently gotten much attention, especially regarding proactive, reactive, and position-based routing protocols. Routing protocols' primary objective is to transmit data packets from their source to their destination. Identifying the best routing protocol is a common problem in Ad Hoc networks. This paper presents a performance evaluation study of proactive, Open Shortest Path First (OSPF), reactive; Ad Hoc onDemand Distance Vector Routing (AODV), and positionbased routing; Location-Aided Routing (LAR1). The QualNet v5.1 simulator was used to conduct the performance evaluation study. The effectiveness of those routing protocols was also assessed using measures of throughput, typical endto-end delay, typical jitter, and energy consumption. This paper depicts that OSPF and AODV have the best performance among the number of packet sizes for the tested protocols.
