Abstract

Rapid advances in recent device technologies continue to create ubiquitous computing environments that have wireless devices everywhere in the surroundings. Positioning devices such as the Global Positioning System (GPS) and pseudolite continue to decrease in price and wireless devices containing them can determine the location of the device itself. Given this background, providing services based on the location information of a device group, in other words, location‐aware services, is currently an active topic. The location‐aware services being widely researched today provide guide systems to users. A typical service is Intelligent Transport Systems (ITS). However, these services are not available in an environment where special positioning devices cannot be used, and the user must switch to another service. Existing services have the drawback of architectures that are greatly affected by the user's environment. Thus, in this paper, we propose seamless location‐aware services that will improve on these conventional services. We present the problems of using existing methods as the routing protocol, which is an element technology of these services; propose and evaluate a method better suited to these services; and verify its effects by a computer simulation. © 2003 Wiley Periodicals, Inc.
