The networking industry has taken an interest in mobile ad-hoc networks (MANETs) due to their desirable features, which include multi-hop routing, self-configuration, self-healing, self-managing, reliability, and scalability. Even in cases where nodes are static, the dynamic nature of connection quality makes routing over wireless mobile networks a crucial concern. The requirement for an effective routing system that determines a route based on specific performance measures connected to the link quality is a major difficulty in MANETs. Finding a good path between the source and destination pairs is typically the focus of the routing problem in MANETs. This indicates that a high throughput routing protocol has to be developed. Investigation is necessary to determine how single-path and multipath routing protocols affect MANET performance. This paper introduces a performance comparison utilising network simulator version 2 (NS-2) of popular routing protocols, including AODV, AOMDV, and OLSR, in terms of throughput, packet delivery, routing overhead, and end-to-end delay.
