Connecting the wired and wireless networks particularly the Mobile Ad hoc NETwork (MANET) is integrated with Internet. Different mechanisms have been proposed to integrate MANETs and the Internet. These mechanisms are differing based on gateway discovery mechanism, and ad hoc routing protocol. When MANET is connected to the Internet, it is important for the mobile nodes to detect an available gateway providing an access to the Internet. This paper is a survey on the Mobile Ad-hoc NETwork (MANET) routing protocols used in gateways.
