Performance evaluation of Manet proactive and reactiverouting protocols using NS3

Abstract

Mobile Ad hoc network which is known as MANET is a network communication medium that is made up of mobile wireless node. The network operates as an infrastructure-less network that doesn’t require an existing network infrastructure such as routers, switches or mounted access point for network communication. MANET is a network which its setup is independent regardless of its location, but has the problem of establishing an effective network route. As wired network communication is governed by topologies, MANET in its application is governed by network routing protocols which are the basis for effective network communication. In this thesis, the routing protocols which includes DSDV, OLSR as Proactive and AOMDV as Reactive routing protocols respectively. Simulated using NS3 at 20, 40 and 60 number of nodes in a real-time scenario. Results obtained shows their performance based on the following parameter metrics: Average Throughput, Average End-to-End Delay and Average Energy Consumption. Overall, the Optimized Link State Routing (OLSR) protocol outperformed the other two routing protocols DSDV and AOMDV for the tested metrics for small networks of 20 number of nodes. Ad hoc On-demand Multipath Distance Vector (AOMDV) performs better at medium networks of 40 number of nodes. While Destination Sequence Distance Vector (DSDV) performs better at larger networks of 60 number nodes. OLSR showed better performance based on the cumulative performance on the network scenario of both small and larger networks, which serves useful information in terms of designing a network.
