Research domains ACMES/MARGE 9

Connectivity and partition detection  Objectives  Mobile Ad-hoc Networks (MANETs) ⇒ Partitionable systems  Partitioning ⇒ Degradation of service, but not necessarily unavailability  Approach  Group Communication System = Membership + Multicast  Proposition  Sequence of Abortable Consensus for group membership  Current interests  Distribution of context information, mobile commerce, pervasive games ACMES/MARGE 10

Consistency and Replication  Objectives  Maintain replicated copies consistency for ubiquitous computing  Consider discrete and continuous applications Synchronization  Approach Game Game Medium Client Client Medium  Consistency management Medium Manager Manager Network as an extra-functional middleware service  Proposition Medium  Synchronisation Medium Manager  RFID-based Distributed Shared Memory Game  Current interests Client  Mobile multiplayer games.  Plug: Secrets of the Museum  RFID/NFC tags hold the system memory  Players constitute the network ACMES/MARGE 11

Context Management  Objectives  Consistent view of the execution context  Identification of adaptation situations  Approach  Imperative approach with a composition language  Proposition  COSMOS middleware  COSMOS DSL  http://picoforge.int-evry.fr/projects/svn/cosmos/  Current interests  Autonomous distributed context management of mobile devices  Adapt to new context data sources, clients, inference rules, etc.  Management of the Quality of context (QoC) ACMES/MARGE 12

Context-awareness  Objectives  Middleware to produce and execute distributed context-aware applications for ambiant computing  Approach  Design: Driven by CA Domain Specific Models  Proposition  Runtime Models to  Drive context management  Notify situations  Reconfigure applications  Update Context Awareness  Current interests  Distributed observation and reconfiguration  QoC aware contracts ACMES/MARGE 13

Service Composition Adaptation and Reconfiguration  Objectives  Ad hoc user task composition in heterogeneous environments considering user preferences  Session continuity of user task (dynamic adaptation at runtime) G T  Approach  Mapping of abstract service composition on available components  Monitoring of used HW and SW component properties  Adaptation of the abstract description G N  Proposition  Resource (device and component) discovery based on UPnP  Dynamic device and component selection  Framework for distributed dynamic monitoring of environment components  Structural runtime adaptation based on injection of patterns  Current interests  Stateful components  Adaptation (interfaces, behaviour…) ACMES/MARGE 14

Autonomic Deployment  Objectives  Autonomic Deployment (i.e. software deployment without user interaction)  Approach  Declarative language to describe the deployment constraints  Adaptive Mobile Agents to support the deployment  Distributed resolution of the deployment process  Proposition  Autonomic Deployment Framework (ongoing work)  Current interests  Deploy middleware for context management from small to big devices  Deploy on Grids or Clouds ACMES/MARGE 15
