The common approach, which we also follow here, is to leave this decision to the mobile node. Before selecting an Internet gateway, an aircraft must first become aware of the gateway ...

Furthermore, we should consider the situation of several mobile networks recursively attached together. The goal of network mobility support is to prov ...
