Implementation of new services to support ubiquitous computing for campus life

The various services that make up the ubiquitous computing concept have developed with the rapid growth of wireless Internet environments and mobile devices. The major purpose of this research is to provide a context-aware U-Town environment to users by utilizing sensors and mobile devices currently available in the public sector and the marketplace. In this paper, the first step of the UTOPIA (Ubiquitous computing TOwn Project: Intelligent context Awareness) project is to introduce the U-Campus service (Ubiquitous computing for the campus). The paper introduces services such as the U-Restaurant, U-Museum, and the U-Theme Park, which are the second step of the U-Town project. In addition, we introduce the MoCE (Mobile Context Explorer) architecture, which is the context-aware recognition technology used to realize U-Town project services.

Design of a Mobile Application Framework with Context Sensitivities

New service concepts involving mobile devices with a diverse range of embedded sensors are emerging that share contexts supporting communication on a wireless network infrastructure. To promote these services in mobile devices, we propose a method that can efficiently detect a context provider by partitioning the location, time, speed, and discovery sensitivities.
