Ad hoc networking allows portable devices to establish communication independent of a centralinfrastructure. However, the fact that there is no central Infrastructure and that the devices can move randomly gives rise to various kind of problems, such as routing and security. In this thesis the problem of routing is considered. This paper addresses issues pertaining to two different routing protocols Destination Sequenced Distance vector (DSDV) and Dynamic Source Routing (DSR) protocols, which

Objective of this paper to show the implementation of two routing protocols using Network Simulators and run it for different number of nodes. Then compared the two routing protocols for different network parameters and studied the efficient protocol under a particular scenario on the basis of two metrics. (1) Packet delivery ratio (2) Routing load DSDV is a Proactive gateway discovery algorithm where the gateway periodically broadcasts a gateway advertisement message which is transmitted after expiration of the gateways timer. DSR is a Reactive gateway discovery algorithm where a mobile device of MANET connects by gateway only when it is needed.
