Cellular IP - a New Approach to Internet Host Mobility
Overview This paper describes a new approach to Internet host mobility. We argue that by separating local and wide area mobility, the performance of existing mobile host protocols (e.g. Mobile IP) can be significantly improved. We propose Cellular IP, a new lightweight and robust protocol that is optimized to support local mobility but efficiently works with Mobile IP to provide wide area mobility support. Cellular IP maintains distributed cache for location management and routing purposes. Distributed paging cache coarsely maintains the position of ‘idle’ mobile hosts in a service area. Cellular IP uses this paging cache to quickly and efficiently pinpoint ‘idle’ mobile hosts that wish to engage in ‘active’ communications. This approach is beneficial because it can accommodate a large number of users attached to the network without overloading the location management system. These distributed location management and routing algorithms lend themselves to a simple and low cost implementation of Internet host mobility requiring no new packet formats, encapsulations or address space allocation beyond what is present in IP.
