A Mobile Ad-hoc Network is defined as a network that is wireless and dynamic. It can be designed with no necessity for prior infrastructure where every node acts as router. A mobile Ad hoc Network is a self-configuring system of mobile nodes that are connected wirelessly. Every node functions as a sink, as well as a router to send packets. These nodes can move freely and independently in any direction and able to get organized into a network. Hence, they change their positions frequently. In this study, a comparison is made between Ad-hoc On Demand Distance Vector protocol and Ad-hoc On Multipath Demand Distance Vector protocol using network simulator NS2.35. AODV is reactive gateway discovery algorithm where a MANET mobile device connects only on-demand. AOMDV was basically made for highly dynamic ad-hoc networks to respond to link breakages and failures in network. It works on sustaining paths for the destinations and uses destination sequence numbers to define the fresh routing information to ensure loop freedom at all times and to avoid problems. It is a protocol based on timer that finds ways for the mobile nodes to respond to breakages in links and changes in topology. Three protocols have been compared together and separately to see their performance. The performance matrix contains Packet Delivery Ratio, End to End Delay, Throughput, and Routing overhead. The comparison of routing protocols’ performance is made under two scenarios when the number of nodes changes, when simulation time changes. The results show that the AODV is better than AOMDV when the number of node increases. On the other hand, the AOMDV has better performance when the simulation increases.
