Protocols for mobile internetworking

We consider the problem of Mobile Internetworking, that is, providing network access to hosts whose physical location changes with time. Such hosts cannot depend on traditional forms of network connectivity and routing, because their location, and hence the route to reach them, cannot be immediately deduced from their network address. The three major points of the thesis, which are a departure from previous approaches, are: ffl Mobility is a network-layer problem, and is best attacked by embedding virtual mobile networks at the proper hierarchical address level. ffl Locality in host mobility, can be taken advantage of in order to yield efficient and practical tracking and routing mechanisms. ffl On-demand acquisition of mobile host location information, which is essentially routing information, yields a system that scales linearly as a function of its size. This dissertation shows the design, implementation and evaluation of IP-based protocols for mobile internetworking. The p...
