Routing Protocols in Mobile Ad Hoc Networks – A Simulation Study Final

Ad-hoc networks are mobile wireless networks that have no fixed infrastructure. There are no fixed routers-instead each node acts as router and forwards traffic from other nodes. MANET (Mobile Ad-Hoc Network) is a type of ad-hoc network with rapidly changing topology. Since the nodes in a MANET are highly mobile, the topology changes frequently and the nodes are dynamically connected in an arbitrary manner. In order to facilitate communication with the network, a routing protocol is used to discover the routes between nodes. Efficient. routing of packet is a primary MANET challenge. Today, there exist various routing protocols for this environment. This paper compares the performance of some of the routing protocols. The performance tests are done by using Network Simulator 2 (ns2)
