Review Techniques and Fundamentals of Internet Access Solutions: MANET-INTERNET Integration Scenario
Mobile Ad-hoc NETworks (MANETs) are formed by the association of the mobile devices, usually capable of multi-hop communication among themselves even if there is no networking infrastructure and central administration to control its operation. Need for the ubiquitous computing lead to connect the MANETs to the fixed IP Network i.e. internet. To connect the MANET to the internet, first it might discover internet gateway through which it can communicate. The discovered gateway may be the mobile node within the MANET or it may be any fixed external node outside the MANET. The gateway works as the default router for all the nodes of the MANET through which all the incoming/outgoing packets are routed between the MANET and the internet.
