Monitoring the Impact of the Nodes Density on the MANETs’ Environment

MANETs (Mobile Ad-hoc Networks) are self-contained systems that can function without the use of centralized controllers, pre-configured paths/routes, or advanced communication structures. A MANET’s nodes are each controlled separately, allowing them to behave in an unrestricted and randomized manner within the MANET. When the node movement arises, the nodes quit their MANET and join other MANETs. In any case, these characteristics may have an adverse effect on the performance of routing protocols and the overall topology of the systems. In a MANET setting, this work evaluates and compares the performance of three routing protocols: AODV, DSR, and DSDV. The research includes running a simulation environment to examine how routing protocols operate when the number of nodes is changes. Since the AODV protocol constructs the route using a demand mechanism, it is more stable than DSDV or DSR when measuring TP and PDR. The DSDV, on the other hand, has a lower delay than other protocol since it builds the route using a table driven mechanism.
