Role of Routing Protocol in Mobile Ad-Hoc Network for Performance of Mobility Models

Abstract

The term "Mobile Ad Hoc Networks" (MANETs) refers to a technology that is currently gaining worldwide popularity. A MANET is a network without any centralized management and without any infrastructure. It is made up of mobile nodes (MNs), which create the network on the fly. Although mobile nodes can quickly change their topology, effective routing protocols are required to build the network connecting nodes for this purpose. A key component of the routing protocol is the ability for mobile nodes to move independently. The network's overall performance may be directly impacted by them. Therefore, the effectiveness of the MANET routing protocol is significantly influenced by node mobility. The movement pattern displays how positions, locations, and node velocities of mobile users change over time in real-world applications. To get the best performance metrics, it is difficult to create an efficient and effective mobility model for MANET. In this study, we discuss the effects of the random walk (RW) and random waypoint (RWP) mobility models on the routing parameters. In the past, different routing systems' effects on network performance have been assessed using mobility models. As a result, the mobility pattern's characteristics will substantially influence how well the network performs. The accurate route adjustments must be rearranged in the correct sequence by the routing protocols. As a result, traffic routing update overheads are very high. These mobility patterns affect various network protocols or applications differently.
