A Platform for Experimenting Disconnected Objects on Mobile Hand-Held Devices

Mobile databases and distributed systems relying on wireless communication networks have to deal with variable levels of connectivity. This demonstration proposes a generic Disconnected Object Management (DOM) service, called , that enables work continuity even when weakly connected or disconnected. For better agility and fidelity, we offer both application-aware and application-transparent adaptations. RESUME. Les bases de donnees mobiles et les systemes repartis utilisant les reseaux sans fil doivent faire face a de fortes variations du niveau de connectivite. Cette demonstration propose un service generique de gestion d’objets deconnectes appele qui permet de continuer a travailler en modes faiblement connecte ou meme deconnecte. Pour ameliorer l’agilite et la fidelite, nous offrons une adaptation transparente pour l’application ainsi qu’une adaptation avec collaboration entre l’application et le systeme.
