Middleware for mobile computing

摘要

Mobile computing has become popularized with the widespread dissemination of small computers, portable devices, PHS and cellular phones. However, the mobile computing environment still has problems; namely, slow and intermittent communicationlinks, and limitations on user interfaces imposed by size constraints.To address these issues, we have developed the Move! (mobile virtual environment) middleware systems. FastMove! speeds up access to the World-Wide Web (WWW) via slow communication links, while using existing WWW software. PortableMove! enables users toobtain their personalized environment at a desktop host at any site, by serving all personal files stored in a portable device to the desktop.
