Mobile Ad-Hoc Networks (MANETs) can be implemented at any time without relying on an infrastructure to initiate a connection in the targeted area between the components of the network. These types of networks are known as self-configured networks and the transmission of the packets are done through the network layer via routing protocols that are responsible for finding the best route between the source node and the destination node. Routing protocols play an important role in terms of the performance of MANETs. Therefore, it is important to study and investigate different routing protocols from different classes of MANET. Routing protocols can be categorised into three categories Hybrid, Reactive, and Proactive. In this work, four routing protocols, AODV, OLSR, DSDV, and DSR, from the Reactive and Proactive categories are investigated and evaluated using the Random Way Point (RWP) mobility model for the performance of a few groups of 50 - 250 nodes using simulation on the NS-3 network simulator. The packet receiving rate and End-to-End delay were analysed for each routing protocol in the determined environment. The results revealed that reactive routing protocols have better performance in low- and medium-density networks than the proactive category. However, in high-density networks, proactive protocols are more efficient, and OLSR, with relatively less delay and more throughput, has the best performance.
