MANET Internet Integration: A Survey Based Study

Mobile ad hoc network being easy to deploy, self organized, flexible and independent of any pre-established infrastructure has become main component of research. But the research in the field of ad hoc network is restricted to stand-alone isolated networks. To widen the network coverage and application domain of ad hoc networks the authors need to integrate the mobile ad hoc networks with Internet. The connection between MANET and Internet is established using a gateway. To access the Internet it is necessary for the mobile nodes in MANET to find out the available gateway which requires a gateway discovery mechanism.
