Abstract
Using the Internet as a foundation for wireless networking, there is currently a great deal of interest in providing IP networking support for mobile hosts. As a result of IPs reliance on the entire Internet address for host identification, most proposals depend on a default route through the mobile host's home address, which makes for unnecessarily long routes. This paper introduces two concepts, “local region” and “patron service”, based on the locality features of host moving and calling patterns. It then shows how these concepts work together to realize a location management scheme for achieving optimal routing for most traffic while restricting costly location propagation. The proposed scheme was implemented using a network simulator and evaluated from routing effectiveness point of view, as compared with its location overhead.
