An Agent-Enabled Systemfor Personalizing Wireless Mobile Services

摘要

Handheld wireless devices such as cellular phones and personal digital assistants (PDAs) have limited memory, storage, andrnprocessing power. In addition, small screens and limited input facilities make entering information tedious. It is thereforernimportant that wireless mobile applications optimize resource usage and minimize input effort imposed on the user. One wayrnis to download to the client only the information most relevant to the user, then present that information effectively, takingrninto account the user's preferences and history as well as the task at hand. This personalization approach minimizes therninformation to be displayed. In this paper, we present a mobile agent-based system for personalizing mobile services; we usernmobile agents simply because such autonomous software entities have characteristics that can benefit mobile devices and thernwireless environment. We introduce the tiered architecture of the proposed system and the functions of the differentrncomponents; then we discuss how we use the Composite/Capabilities Preferences/Profile (CC/PP) in personalizing wirelessrnmobile services. A proof of concept implementation has been developed using Java technologies.
