Impact Analysis of Various Parameters on the Performance of AODV Routing Protocol in MANET using NS-3 Simulator

For a Mobile Ad Hoc Network (MANET) protocol to transmit data as efficiently as possible, the appropriate settings are needed. Use of the routing protocol's default parameter values and the proper routing protocol selection are required to solve this issue. Mobile Ad hoc Networks (MANETs) nodes connect wirelessly without a specific administrative framework or infrastructure. Due to node movement and battery capacity limitations, routing decisions in MANETs are constantly subject to route failure. Because it reacts quickly to changes in the topological network, the on demand routing protocol known as Ad hoc On Demand Distance Vector (AODV) is frequently employed. It does not, however, take into account the state of the nodes and links, which may cause a decline in routing performance owing to node or link failure.A recent and ongoing networking tool for research is Network Simulator, notably in the field of mobile networking. Creating and analyzing network protocols, such as the AODV routing scheme in MANET, is made simpler by network simulation. Multiple AODV routing protocol characteristics are supported by the active open source discrete event simulator NS-3 in MANET. In this article, the performance of the AODV routing protocol was investigated using NS-3 and three network topologies: Laptop-Wifi, Laptop-Laptop, and Laptop-Lan. The metrics were studied using the same simulation parameters by assembling the output of all three networks.
