Abstract

Mobile internetworking revolves around the premise that a mobile host (MH) will frequently attach to and detach from the Internet, thus changing its address frequently. Location management in mobile internetworking refers to the process of keeping track of the current addresses of MHs in the Internet. Protocols proposed for mobile internetworking rely on a combination of searches and updates for location management. A drawback of these protocols is that they are not uniformly efficient over all possible call-to-mobility ratios (i.e., the relative frequency of searches as compared to updates) . An important issue, therefore, is how the overall costs of location management can be reduced, regardless of the call-to-mobility ratio. The aim of this work is to explore a new and practical scheme for location management, with emphasis on network cost reduction.
