Modelling with Ubiquitous Agents a Web-Based Information System Accessed Through Mobile Devices

摘要

This paper describes PUMAS, our proposal of architecture which uses ubiquitous agents in order to give to nomadic users (users who often change of location) access to a Web Information System (WIS) through their Mobile Devices (MDs). PUMAS focuses on the exchange of information between MDs seen as peer ubiquitous agents and takes into account the user's needs, location and the limited configuration of her/his MD for displaying the information. PUMAS also handles two important aspects of a nomadic use of a WIS: user location (provided by a GPS device) and information distribution among several heterogeneous MDs (controlled by a Peer to Peer approach). In addition, we present the Agent Class Diagram and the Interaction Diagrams of PUMAS in the Agent UML (AUML) notation. An application relying on PUMAS is described.
