Ad hoc networks were initially conceived as stand-alone entities without connection to any external infrastructure. A possible solution to give access to ad hoc terminals to the Internet trough conventional WLAN networks is described in the mobile multi-gateway support. This scheme proposes to utilize a mobile node within the transmission range of the WLAN access point (AP) as a connecting gateway between the MANET and the Internet. As the gateway can move freely, its functionality can be switched to another node present in the cover area of the access point acting as a router. In any case, all the traffic flowing from/to Internet passes through the same node, which can impose a bottleneck in the system. In this paper, a light modification is suggested to distribute the Internet traffic among different gateways.
