The connection of ad hoc network to the internet is established using gateways. To start the internet connection in MANET, first process is that the gateway is to be discovered by the mobile nodes. As the internet is the global service the user are to be satisfied by the integration of internet with the MANET. For integration of two networks the gateway is used as the bridge. In this paper the AODV reactive routing protocol is used for avoiding the scarcity of network resources in MANET. The authors have designed and analyzed the various gateway discovery approaches and the stimulation is carried out by NS2 which is used for all network scenarios.
