The Mobile Internet Router will act as an interface between the wired network and an ad-hoc network. In other words, these routers will act as a Mobile Node that roams between heterogeneous access networks. This roaming capability is required for the mobile router to maintain a constant connection, either via WLAN or General Packet Radio Service (GPRS). WLAN access is required to be online when high data bandwidth is available.

Under this scenario, the mobile terminals in ad-hoc networks communicate with each other through ad-hoc communication protocols. Among mobile terminals, some of them can directly connect to the Internet and serve as Access Points for the rest of the mobile terminals in the Internet mobile ad-hoc network. Therefore, an Access Point will provide a gateway for the Internet, and is assumed to have access to any information.

In the future, there'll be a need for non-infrastructure IP domains in order to exchange data between mobile users. This type of interaction between mobile users can be provided by ad-hoc protocols, which allow IP connectivity in a limited domain without Internet access. There will be scenarios in the future where ad-hoc users want Internet access via routers to be online.

In this case, the entire ad-hoc network can be attached via one router to the Internet, where the router is part of the ad-hoc domain. In scenarios where the ad-hoc network is stationary, located on different objects, such as in trains, planes, and buses, the router must have a wireless link to the Internet. General Packet Radio Service connectivity is required when an ad-hoc network has to provide high mobility, as in vehicles with high velocity. GPRS offers high mobility and always on connectivity, but with low bandwidth. This can be supported by WLAN access with high data bandwidth.

In conclusion, one of the active research topics is the connectivity of mobile ad-hoc networks with the Internet. There are a number of different constraints associated with mobile terminals as an obstacle in figuring out the final model of Internet mobile ad-hoc networks. Not all mobile terminals can access the Internet. Due to mobility, a set of mobile terminals can be separated from the rest of the network and get disconnected from the Internet. Finally, a mobile terminal requiring multi-hop connection to access the Internet may incur longer access time than those that have direct access to the Internet. Resolution of these issues could provide a good means of information access over the Internet in a highly dynamic environment.
