Performance evaluation of generic routing protocols in mobile ad hoc networks

Abstract

Mobile Ad hoc Network or MANET in short is a self-configuring and infrastructure-less network of mobile nodes or devices that are connected wirelessly. There is no local base yet every device in a MANET is allowed to move autonomously in any pattern, consequently changing its connection to different devices much of the time. Each must act as a router and forward traffic. Each device or node participating in a MANET forwards data for other nodes, so the nodes forwarding data are dynamically determined on the basis of network connectivity. Ad hoc networks can use flooding for forwarding data. Mobile Ad-hoc networks generally have a routable systems network environments on top of the link layer. The decentralized nature of mobile ad hoc systems makes it suitable for a mixture of applications where local nodes can't be depended on and can enhance the versatility of networks in correlation from managed wireless networks. In my thesis, I’ve evaluated and implemented mobile ad hoc protocols in NS2 simulator and compared the routing protocols under different network parameters. The following protocols have been taken from three different categories:- i) Reactive Routing – DSR, AODV ii) Hybrid Routing – ZRP
